Generally, the carbohydrate part(s) play an integral role in the function of a glycoconjugate; prominent examples of this are neural cell adhesion molecule (NCAM) and blood proteins where fine details in the carbohydrate structure determine cell binding (or not) or lifetime in circulation.
Carbohydrate metabolism is the whole of the biochemical processes responsible for the metabolic formation, breakdown, and interconversion of carbohydrates in living organisms. Carbohydrates are central to many essential metabolic pathways . [ 1 ]
Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [1] Carbohydrases are produced in the pancreas, salivary glands and small intestine, breaking down polysaccharides.
The term "carbohydrate" (or "carbohydrate by difference") refers also to dietary fiber, which is a carbohydrate, but, unlike sugars and starches, fibers are not hydrolyzed by human digestive enzymes. [5] Fiber generally contributes little food energy in humans, but is often included in the calculation of total food energy. The fermentation of ...
Glycosylation is the process by which a carbohydrate is covalently attached to a target macromolecule, typically proteins and lipids. This modification serves various functions. [5] For instance, some proteins do not fold correctly unless they are glycosylated. [2]
The seed cannot produce biomass using photosynthesis because of lack of an organ to perform this function. The lipid stores of germinating seeds are used for the formation of the carbohydrates that fuel the growth and development of the organism. The glyoxylate cycle can also provide plants with another aspect of metabolic diversity.
However, the structure of the binding site of numerous lectins, enzymes and other carbohydrate-binding proteins has revealed a wide variety of the structural basis for glycome function. The purity of test samples have been obtained through chromatography ( affinity chromatography etc.) and analytical electrophoresis ( PAGE (polyacrylamide ...
Oligosaccharides are carbohydrates that consist of a polymer that contains three to ten monosaccharides linked together by glycosidic bonds. Glucose reacts with oxygen in the following reaction, C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O. Carbon dioxide and water are waste products, and the overall reaction is exothermic .
