Resumen

Abstract: Carbohydrates are widespread in biological systems and are often associated with many specific recognition and signaling processes that lead to important biological functions and diseases. Considerable efforts have been directed toward understanding and mimicking such recognition processes, and developing effective agents to control these events. The pace of discovery research in glycobiology and development of carbohydrate-based therapeutics, however, has been relatively slow compared to that of other classes of biomolecules due to the lack of appropriate strategies and methods avai

Resumen

Carbohydrates are crucial for living cells, playing myriads of functional roles that range from being structural or energy-storage devices to molecular labels that, through non-covalent interaction with proteins, impart exquisite selectivity in processes such as molecular trafficking and cellular recognition. The molecular bases that govern the recognition between carbohydrates and proteins have not been fully understood yet. In the present study, we have obtained a surface-area-based model for the formation heat capacity of protein–carbohydrate complexes, which includes separate terms for the

Resumen

High carbohydrate food has been perceived as a food with high glycemic index (GI). Meanwhile, the risks of diabetes are frequently associated with the GI carbohydrate based foods. Therefore, a comprehensive study based on the literature review regarding the relationship between high-carbohydrate food and the glycemic index needs to be conducted. High-carbohydrate foods can be grouped into the available carbohydrates type and non-available carbohydrates type. Food with available carbohydrates such as glucose, disaccharide, digestible oligosaccharides, and starch have positive correlation with t

Resumen

There is consensus that carbohydrate foods, in the form of fruit, vegetables and whole-grain products, are beneficial to health. However, there are strong indications that highly processed, fibre-depleted, and consequently rapidly digestible, energy-dense carbohydrate food products can lead to over-consumption and obesity-related diseases. Greater attention needs to be given to carbohydrate bioavailability, which is determined by the chemical identity and physical form of food.

Many birds exhibit seasonal switches in diet and thus alter the nutrients predominating their food intake. We tested for dietary modulation of small intestine (SI) enzymes in yellow-rumped warblers, a species for which such diet changes are well documented. Birds were fed three diets formulated from either fruit, insect, or seed. We predicted that SI carbohydrases and peptidases would be modulated in direct correlation with relative levels of dietary carbohydrate and protein, respectively. Aminopeptidase N activity was about twice as high in birds eating the highest protein content diet. In co

The conformational analysis of such ligands in solution and bound to receptor proteins, in conjunction with docking studies, reveals major aspects of the carbohydrate-protein recognition process at a molecular level. This knowledge is of practical importance for the rational

Resumen

D- and most L-enantiomers of carbohydrates and carbohydrate-containing compounds occur naturally in plants and other organisms. These enantiomers play many important roles in plants including building up biomass, defense against pathogens, herbivory, abiotic stress, and plant nutrition. Carbohydrate enantiomers are also precursors of many plant compounds that significantly contribute to plant aroma. Microorganisms, insects, and other animals utilize both types of carbohydrate enantiomers, but their biomass and excrements are dominated by D-enantiomers. The aim of this work was to review the cu

Resumen

AbstractThe purpose of the present review is to describe how human physiology at very low carbohydrate intakes relates to the criteria for nutritional essentiality. Although we did not limit ourselves to one particular type or function of carbohydrates, we did primarily focus on glucose utilisation as that function was used to determine the recommended daily allowance. In the general population, the human body is able to endogenously synthesise carbohydrates, and does not show signs of deficiency in the absence of dietary carbohydrates. However, in certain genetic defects, such as glycogen sto

Resumen

Digestive enzyme activity and capacity (activity x tissue weight) for protein (total protease assay, 25° C) and carbohydrates (total carbohydrase and alpha-glucosidase assay at 5, 18 and 25° C) was investigated for the carnivorous stargazer, Uranoscopus scaber along its digestive tract. Results indicated that whole gut total protease activity was highest at pH 1.5 (P<0.05) (25° C) in U. scaber, (6.64±2.55 mg tyrosine per g digestive tract per minute, pH 1.5). Total protease activity was apparent mainly in the stomach at pH 1.5 (9.73±3.3), and to a lesser degree in the anterior intestine (11

Resumen

Understanding the carbohydrate dynamics of sprouting Cirsium arvense (L.) Scop. and Sonchus arvensis L. ramets can assist in optimizing perennial weed management. However, detailed knowledge about general reserve dynamics, minimum values in reserves (compensation point) and different reserve determination methods remains sparse. We present novel insights into reserve dynamics, which are especially lacking for S. arvensis. We uniquely compare root weight changes as a proxy for carbohydrates with direct carbohydrate concentration measurements using high-performance liquid chromatography (HPLC).

Resumen

Carbohydrate-binding modules (CBMs) are discrete parts of carbohydrate-hydrolyzing enzymes that bind specific types of carbohydrates. Ultra high-resolution X-ray crystallographic studies of CBMs have helped to decipher the basis for specificity in carbohydrate–protein interactions. However, additional studies are needed to better understand which structural determinants confer which carbohydrate-binding properties. To address these issues, neutron crystallographic studies were initiated on one experimentally engineered CBM derived from a xylanase, X-2 L110F, a protein that is able to bind seve

Resumen

Cranberry (Vaccinium macrocarpon Ait. cv. Searles) vegetative tissue was analyzed at various stages of development to determine carbohydrate levels under field and greenhouse conditions and to identify the carbohydrates. Except during dormancy, cranberry uprights in the field had the highest concentration of carbohydrates (soluble and starch) at early blossom, when the lower flowers were at anthesis. As early flowers developed into fruit and upper flowers were at or just beyond anthesis, uprights had lower carbohydrate concentrations. As fruit growth slowed, soluble carbohydrate levels increas

AbstractPreviously, we reported seasonal variation in iodine contents in the seagrass Zostera marina. Herein, we sought the factors controlling this variation, and investigated relationships between iodine and carbohydrate contents, using extracts and residues of seagrass samples extracted with 0.1 N HCl. In plants, carbohydrates in HCl-extracted and residual fractions are considered to represent storage and structural carbohydrates, respectively. On average, 44% and 56% of total iodine in samples was contained in the HCl-extracted and residual fractions, respectively. Both HCl-extracted and r

Brain diseases, like majority illnesses, are influenced in some way by nutrition. Alzheimers disease, which is characterized by brain cell deaths and memory loss, is significantly influenced by sugar intake. The frequency, quantity, and type of carbohydrates can influence AD development and outcomes. Whether highly processed or not, carbohydrate-rich foods influence AD. This paper discusses how a high-carbohydrate diet increases the chances of AD development and aggravation. General introduction to carbohydrate diets and the etiology of AD are explained.

Resumen

Although the benefits of regular exercise on cardiovascular risk factors are well established for people with type 1 diabetes (T1D), glycemic control remains a challenge during exercise. Carbohydrate consumption to fuel the exercise bout and/or for hypoglycemia prevention is an important cornerstone to maintain performance and avoid hypoglycemia. The main strategies pertinent to carbohydrate supplementation in the context of exercise cover three aspects: the amount of carbohydrates ingested (i.e., quantity in relation to demands to fuel exercise and avoid hypoglycemia), the timing of the intak
