Annotation:
The electronic nature of various C-substituted nitrones was investigated by IR spectroscopy and 13C NMR as well as MNDO calculations. These include α-methoxy nitrones (imidate N-oxides) RC(OMe)=N(O)t-Bu with R = p-MeOC6H4 (Ia), C6H5 (Ib), p-NO2C6H4 (Ic), and H (Id) and nitrones YCH=N(O)t-Bu with Y = CN (IIIa), n-BuS (IIIb), C6H5CH2NH (IIIc). Upfield 13C shifts of C(α), the iminyl (C=N) carbon, of imidate N-oxides I versus the corresponding imidates are less than the usual upfield shifts of imine N-oxides versus imines, suggesting less buildup of electron density on C(α) in the case of alcoxy nitrones. Charge density and π bond order values from MNDO calculations for C-methoxy-C-phenyl nitrones versus model systems confirm this result and indicate a more localized C=N π bond in nitrones bearing an α-methoxy group. For N-tert-butyl nitrones with an α heteroatom (nitrogen or sulfur), phenyl, or cyano group, C(α) shifts move downfield for π-donating groups and upfield for π-accepting groups. This "reverse substituent effect" as well as C=N stretching frequencies can also be readily explained by C=N π bond containment by lone pair groups. The reported enhanced cycloaddition reactivity of α-alkoxy nitrones and their electrochemical behavior are discussed in terms of HOMO energy levels.

Annotation:
The redox behavior of various C-substituted nitrones was investigated by cyclic voltammetry in acetonitrile. These included C-methoxynitrones (MeO)CR = N(O)t-Bu with R = C6H5(1a), p-MeOC6H4 (1b), p-NO2C6H4 (1c), and H (1d) and nitrones YCH = N(O)t-Bu with Y = n-BuS (2a), CN (2b), and C6H5NH (2c). All gave anodic peaks which can be identified as oxidations of the nitrone function. Controlled potential electrolysis of 1a at 1.05 V (SCE) showed that its oxidation was a one-electron process. Reduction of 1a occurs stepwise at −2.08 and at −2.47 V, the same potential for reduction of methyl N-tert-butylbenzimidate (MeO)CPh = Nt-Bu. With electrochemical windows of ca. 3 V, all of the nitrones studied appear suitable for spin-trapping experiments.

Annotation:
The β -amino-hydroxylamines 5a - d are prepared of the α-amino-oximes 1a - d with boranedimethylsulfide. With mercury-EDTA, 5a - d react to (E/Z)-oxime-lactams 3a - d and benzaldoxime 7. Additionally 5b,c give the bicyclic amidine-N-oxides 8b,c, which slowly hydrolyze to the hydroxylamine-lactams 9b,c. These are easily oxidized to (E/Z)-3b,c. Postulated as intermediates in the mercury-assisted reduction of 5, the cyclic hydroxylamines 10a - d are available from the nitrones 4a - d with LiAlH4. From 10a - d with mercury-EDTA the same products are obtained as from 5a - d but without 7. Only the pyrrolidine 10a forms besides (E/Z)-3a the nitrone 4a. Thinlayer chromatography shows that the pure isomers of 3a - d in solution isomerize, contrary to the amine-oximes 1a - d. The configuration of the oxime-lactams depends on the manner of preparation. With mercury-EDTA, 1b,c yield 3b,c with retention of the configuration, while the oximation of phenacyl-lactams 13b,c give rise to (E/Z)-mixtures of 3b,c. The condensed imidazoles 12 result from the nitrones 4a - d and the dihydrooxadiazines 2a,d on treatment with hydrogen chloride.

Annotation:
Chiral β-amino alcohols were successively prone to N-benzylation, O-allylation and oxidation of the resulting benzylamino group to give nitrones 3 which on hydrolysis afforded chiral hydroxylamines HO-NH-CH(R)-CH2-O-CH2-CH=CH2 ((S)-4: R = Me, Bn, iPr. (R)-4: R = Et). Swern oxidation of methyl 2,2-dimethyl-3-hydroxypropionate (16) and treatment of the resulting aldehyde 17 with hydroxylamines (S)-4b (R = Bn) or (R)-4d (R = Et) provided nitrones 18 that underwent an intramolecular 1,3-dipolar cycloaddition on heating yielding the bicyclic β-amino-acid esters 19b and ent-19d, respectively.Reductive cleavage of the N,0- bond of compounds 19 afforded the eight-membered ring compounds 20b and ent-20d, respectively.N-Benzylalaninol (22) was treated with /3-bromo-methacrylate to give the amino alcohol 23. Swern oxidation and subsequent treatment with N-ferf-butylhydroxylamine provided the bicyclic ester 26a (R = t-Bu) via the corresponding nitrone 24. Oxime 25 was prepared in an analogous way as 24 with unsubstituted hydroxylamine. It underwent an intramolecular 1.3- dipolar cycloaddition yielding 26b on heating in toluene. Reduction of 26a afforded the pyrrolidine-carboxylic ester 27a.

The N-allylindole-2-carbaldehydes (5)-(8) and related methyl ketones (9)-(12) undergo reaction with N- methylhydroxylamine to give the cycloadducts (14)-(17) and (19)-(22), respectively. These adducts contain isoxazolidine rings fused to pyrrolo [1,2-a] indole systems. Corresponding cycloaddition of the N- propargylindole derivatives (24) and (25) could not be effected and the nitrone (26) was isolated. The adducts (14)-(17) underwent hydrogenolysis of the isoxazolidine N-O bond to give the amino alcohols (27)-(30), together with traces of the alcohols (31)-(34). X-Ray crystallographic data for the cycloadducts (15) and (16b) are presented.

Ph.D.
Chiral amines are ubiquitous in natural products and are found in many drugs and drug candidates. Enantiopure sulfinimines [RS(O)N=CHR1] are useful chiral building blocks for the stereoselective synthesis of amines and amine derivatives. The aim of this thesis research is to develop new methods to access chiral amine building blocks for applications in the synthesis of nitrogen-heterocycles including ring-substituted tropinones, tropanes, cyclic cis-beta-amino acid derivatives, and amino-cyclopentitols.

Annotation:
Although sorghum malt is relatively rich in free amino nitrogen (FAN), the 150 mg FAN/L threshold recommended for brewing is difficult to obtain. The vitreous nature of the sorghum endosperm hinders proteolysis during brewing. Hence, exogenous proteolytic enzymes are often required to increase hydrolysis of sorghum malt protein to produce sufficient FAN in order to support rapid yeast growth during fermentation. Ten exogenous proteases were examined for their production of FAN in sorghum malt mashing. Mashing was done at 550C for 45 minutes. Levels of FAN, as determined by the ninhydrin method, showed great variation among the proteolytic enzymes, ranging from 96 in control to 182 mg/100 g malt with possibly of most effective proteolytic enzyme. The variation in FAN level was possibly due to different optimal mashing conditions of exogenous proteases used and perhaps due to low ratios of exopeptidase/endopeptidase in the enzyme preparations. Low temperature (400C) and long duration mashing for (7 hours) gave good FAN production during mashing to a total of 113 and 138 mg/100 g malt in control and the treatment with exogenous proteolytic enzyme Flavourzyme plus malt, respectively. The exogenous enzyme (Flavourzyme) plus potassium metabisulphite (PMB) increased FAN production during mashing in the ratio of 2 to 1 in a treatment where PMB was added compared to one without. Similarly, hot wort extract (HWE) increased by 8% during mashing with exogenous enzyme plus PMB compared to one without PMB, respectively. PMB was involved in destabilizing the disulphide bonds in the sorghum protein polypeptide chains allowing proteolytic enzymes better accessibility to proteins. The increase in HWE was possibly due to the starch being freed from the sorghum protein matrix. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) showed some oligomeric and polymeric kafirins after mashing. With transmission electron microcopy (TEM), protein bodies of varying sizes with partially degraded peripheral edges and some holes were seen after mashing. SDS-PAGE and TEM results suggest insufficient proteolysis. High protein digestibility sorghum’s potential for brewing was examined with reference to FAN production. Although during mashing FAN increased by approx. 82 and 115% for unmalted normal and high digestibility sorghums, respectively, the 150 mg FAN/L threshold, recommended for brewing was not achieved. FAN production to levels above 150 mg/L may only be realized if normal sorghum malt or high protein digestibility sorghum malt is mashed with exogenous enzymes containing sufficient exopeptidases coupled with appropriate mashing conditions.

Annotation:
About 14 per cent of the human body is protein, so a growing child, or pregnant woman must have protein intake to increase the total amount of protein in the body, or foetus, as it grows. But why does an adult, whose body weight does not change, require protein in the diet? ‘Protein nutrition’ explains that proteins contain the element nitrogen in their constituent amino acids. Nitrogen balance is the difference between the intake of nitrogen-containing compounds in the diet and the excretion of nitrogen-containing compounds from the body. There is a requirement for dietary protein as the continual breakdown of tissue proteins in the body needs replacement by newly synthesized protein.

Annotation:
Lysinuric protein intolerance (LPI) is an inherited aminoaciduria caused by defective cationic amino acid transport at the basolateral membrane of epithelial cells in intestine and kidney. LPI is caused by mutations in the SLC7A7 gene, which encodes the y+LAT-1 protein, the catalytic light chain subunit of a complex belonging to the heterodimeric amino acid transporter family. Symptoms usually begin after weaning with refusal of feeding, vomiting, and consequent failure to thrive. Hepatosplenomegaly, hematological anomalies, and neurological involvement including hyperammonemic coma will progressively appear. Lung involvement (specifically pulmonary alveolar proteinosis), chronic renal disease that may lead to end stage renal disease, and hemophagocytic lymphohistiocytosis with macrophage activation all represent complications of LPI that may appear at any time from childhood to adulthood. The great variability of the clinical presentation frequently causes misdiagnosis or delayed diagnosis. The basic therapy of LPI consist of a low-protein diet, low-dose citrulline supplementation, nitrogen-scavenging compounds to prevent hyperammonemia, lysine, and carnitine supplements.

Annotation:
The book ends with a chapter devoted to discussing interactions between microbes and higher plants and animals. Symbiosis is sometimes used to describe all interactions, even negative ones, between organisms in persistent, close contact. This chapter focuses on interactions that benefit both partners (mutualism), or one partner while being neutral to the other (commensalism). Microbes are essential to the health and ecology of vertebrates, including Homo sapiens. Microbial cells outnumber human cells on our bodies, aiding in digestion and warding off pathogens. In consortia similar to the anaerobic food chain of anoxic sediments, microbes are essential in the digestion of plant material by deer, cattle, and sheep. Different types of microbes form symbiotic relationships with insects and help to explain their huge success in the biosphere. Protozoa are crucial for wood-boring insects, symbiotic bacteria in the genus Buchnera provide sugars to host aphids while obtaining essential amino acids in exchange, and fungi thrive in subterranean gardens before being harvested for food by ants. Symbiotic dinoflagellates directly provide organic material to support coral growth in exchange for ammonium and other nutrients. Corals are now threatened worldwide by rising oceanic temperatures, decreasing pH, and other human-caused environmental changes. At hydrothermal vents in some deep oceans, sulfur-oxidizing bacteria fuel an entire ecosystem and endosymbiotic bacteria support the growth of giant tube worms. Higher plants also have many symbiotic relationships with bacteria and fungi. Symbiotic nitrogen-fixing bacteria in legumes and other plants fix more nitrogen than free-living bacteria. Fungi associated with plant roots (“mycorrhizal”) are even more common and potentially provide plants with phosphorus as well as nitrogen. Symbiotic microbes can provide other services to their hosts, such as producing bioluminescence, needed for camouflage against predators. In the case of the bobtail squid, bioluminescence is only turned on when populations of the symbiotic bacteria reach critical levels, determined by a quorum sensing mechanism.

Surface treatment of polyolefines by atmospheric-pressure dielectric barrier discharges (DBDs) in virtually oxygen-free nitrogen-containing gases was studied in situ byFourier transform infrared spectroscopy in the attenuated total reflection mode (FTIR-ATR)in order to follow the plasma-chemical generation of chemical functional groups and their further temporal development in the presence of inert or reactive atmospheres.Polyolefin thin films of thicknesses between 50 and 200 nm were prepared directly on ZnS ATR crystals by spin-coating from hot solutions of linear low-density polyethylene (LLDPE), low density polyethylene (LDPE), or polypropylene (PP) in hydrocarbons solvents like xylene or decalin. After the exposure to the afterglows of DBDs in N2 or in mixtures of N2 with H2 or NH3, infrared spectra were taken in situ under inert conditions and after controlled exposure to various reagents, resp., such as water vapor or oxygen. In order to unravel the complex spectra which are generally due to several functional groups with overlapping vibrational bands, exchange reactions with vapor of heavy water (D2O) was applied in order to identify groups which are known to exhibit a rapid H/D exchange like >N=H (imine), -NH2(prim. amine), >NH (sec. amine), -CO-NRH(prim. or sec. amide), using characteristic ratios of wavenumber ratios for corresponding vibrational bands in the deuterated and the protonated moiety.In addition, reactions of the plasma-treated surface with vapors of4-(trifluoromethyl)-benzaldehyde (TFBA) or4-(trifluoromethyl) phenyl isothiocyanate (TPI) were studied by FTIR-ATR in situ. Based on these experiments, tentative assignments of the observed vibration bands to imino, amino, and amido groups are made and interpreted in terms of feasible or probable chemical mechanisms.

The aim of the work was to optimize the process of obtaining multicomponent protein compositions with high biological value and higher functional properties than the original vegetable protein products. Was realized studies to obtain biocomposites on the base of pea protein-oat protein and pea protein-rice protein. Developed composites were enriched with all limited amino acids. For each of the essential amino acids, the amino acid score was 100% and higher. Protein products used in these compositions are not in major allergen list, which allows to use these compositions in allergen-free products and specialized nutrition. To determine biosynthesis parameters for compositions from pea protein and various protein concentrates with the use of transglutaminase enzyme, was studied effect of concentration and exposition time on the amount of amino nitrogen released during the reaction. Decreasing of amino nitrogen in the medium indicated the occurrence of a protein synthesis reaction with the formation of new covalent bonds. Were determined optimal parameters of reaction: the hydromodule, the exposure time, the concentration of EP of the preparation, were obtained mathematical models. Studies on the functional properties of composites, the physicochemical properties of the proteins that make up their composition, and structural features will make it possible to determine the uses in the manufacture of food products based on their ability to bind fat, water, form foam, gels, and etc.

Peptones are protein hydrolysis products consisting of a mixture of free amino acids, oligopeptides, and other fragmented protein components easily digestible by microorganisms. This study aimed to investigate the effect of crude ficin enzyme on the characteristics of peptones derived from yellowfin tuna (Thunnus albacares) dark meat and their potential application in microbial growth. Crude ficin enzyme concentrations used to produce peptones from yellowfin tuna dark meat were 0%, 0.1%, 0.2%, 0.3%, and 0.4%. The results showed that using crude ficin enzyme impacted the characteristics of peptones from yellowfin tuna dark meat, including protein content, amino nitrogen, degree of hydrolysis, and optical density. The research findings revealed protein content of 16.20%-32.51%, amino nitrogen of 2.74%-6.53%, hydrolysis degree of 28.37%-39.16%, and optical density value of 0.342-0.574. The optimal concentration of crude ficin enzyme, based on the results obtained in this study, 0.2% crude ficin enzyme was used for producing peptone from yellowfin tuna (Thunnus albacares) dark meat. .

Experiments involving a winter wheat (Triticum aestivum L.) variety ‘Širvinta 1’ were conducted at the Experimental Station of the Aleksandras Stulginskis University during the period 2006–2009 in limnoglacional silty loam on morainne clay loam Cal(ca)ri-Endohypogleyic Luvisol. Winter crops were grown on the background of N150P90K90 mineral fertilization and were additionally foliar-fertilized with amide nitrogen fertilizer, containing different concentrations of amino acids (0.5 %–3.0 %), at a winter wheat booting, heading and milk maturity stages. Experimental evidence showed that solutions with different amino acids concentrations applied for winter wheat fertilization at booting, heading and milk maturity stages increased plant photosynthetic indicators. Chlorophyll a to b ratio in winter wheat leaves significantly increased having applied 0.5–2.5 % amino acids solutions at booting and at milk maturity stages. Plants fertilized with amino acids solutions at booting stage had a possibility to form larger assimilating leaf area. Winter wheat grain yield significantly increased (0.27–0.4 t ha-1) under the effect of amino acids. The highest yield increases were obtained having applied amino acids at booting and heading growth stages. The statistical data analysis (xextr.) evidenced that the highest yield and its quality would be attained with foliar feeding of winter wheat with amino acids fertilizers: at booting stage with 2.4 %, at heading stage with 1.47 %, and milk maturity stage with 1.39 % amino acids solution.

Effect of Rumen Available Protein, Amimo Acids and Carbohydrates on Microbial Protein Synthesis, Amino Acid Flow and Performance of High Yielding Cows.

Annotation:
The effect of rumen available protein amino acids and carbohydrates on microbial protein synthesis, amino acid flow and performance of high yielding dairy cows was studied. A significant relationship between the effective degradabilities of OM in feedstuffs and the in vivo ruminal OM degradation of diets of dairy cows was found. The in situ method enabled the prediction of ruminal nutrients degradability response to processing of energy and nitragenous supplements. The AA profile of the rumen undegradable protein was modified by the processing method. In a continuous culture study total N and postruminal AA flows, and bacterial efficiency, is maximal at rumen degradable levels of 65% of the CP. Responses to rumen degradable non carbohydrate (NSC) were linear up to at least 27% of DM. Higher CP flow in the abomasum was found for cows fed high ruminally degradable OM and low ruminally degradable CP diet. It appeared that in dairy cows diets, the ratio of rumen degradable OM to rumenally degradable CP should be at least 5:1 in order to maximize postruminal CP flow. The efficiency of microbial CP synthesis was higher for diets supplemented with 33% of rumen undegradable protein, with greater amounts of bacterial AA reaching the abomasum. Increase in ruminal carbohydrate availability by using high moisture corn increased proportions of propionate, postruminal nutrients flow, postruminal starch digestibility, ruminal availability of NSC, uptake of energy substrates by the mammory gland. These modifications resulted with improvement in the utilization of nonessential AA for milk protein synthesis, in higher milk protein yield. Higher postruminal NSC digestibility and higher efficiency of milk protein production were recorded in cows fed extruded corn. Increasing feeding frequency increased flow of N from the rumen to the blood, reduced diurnal variation in ruminal and ammonia, and of plasma urea and improved postruminal NSC and CIP digestibility and total tract digestibilities. Milk and constituent yield increased with more frequent feeding. In a study performed in a commercial dairy herd, changes in energy and nitrogenous substrates level suggested that increasing feeding frequency may improve dietary nitrogen utilization and may shift metabolism toward more glucogenesis. It was concluded that efficiency of milk protein yield in high producing cows might be improved by an optimization of ruminal and post-ruminal supplies of energy and nitrogenous substrates. Such an optimization can be achieved by processing of energy and nitrogenous feedstuffs, and by increasing feeding frequency. In situ data may provide means for elucidation of the optimal processing conditions.

This research project entitled "Influence of Ruminal Starch Degradability on Performance of High Producing Dairy Cows" had the following objectives: a) Determine effects of feeding varying amounts of ruminally degradable starch (RDS) on efficiency of milk and milk protein production; and 2) Investigate digestive and metabolic mechanisms relating to lactation responses to diets varying in ruminal and total starch degradability. Four lactation studies with high producing cows were conducted in which steam-flaked (~ 75% RDS) was compared with dry-rolled sorghum (~ 50% RDS) grain. All studies demonstrated increased efficiency of conversion of feed to milk (FCM/DMI) and milk protein as amount of RDS in the diet increased by feeding steam-flaked sorghum. As RDS in diets increased, either by increased steam-flaked sorghum, grinding of sorghum, or increasing the proportion of wheat to sorghum, so also did ruminal and total tract digestibilities of starch and neutral-detergent soluble (NDS) carbohydrate. Despite other research by these two groups of workers showing increased non-ammonia N (NAN) flowing from the rumen to the duodenum with higher RDS, only one of the present studies showed such an effect. Post-absorptive studies showed that higher dietary RDS resulted in greater urea recycling, more propionate absorption, a tendency for greater output of glucose by the liver, and increased uptake of alpha-amino nitrogen by the mammary gland. These studies have shown that processing sorghum grain through steam-flaking increases RDS and results in greater yields and efficiency of production of milk and milk protein in high producing dairy cows.
