Carbohydrates are diverse bio-macromolecules with highly complex structures that are involved in numerous biological processes. Well-defined carbohydrates obtained by chemical synthesis are essential to the understanding of their functions. However, synt
The presence of asymmetrical carbons in monosaccharides with different functional groups attached gives rise to optical activity. Monosaccharides are optically active, which means that if polarized light is passed through a solution of these compounds, the plane of light will be rotated to the left ...
Those composed of four carbon atoms are called tetroses, those with five carbons are called pentoses, those of six carbons are hexoses, and so on. The most important monosaccharides in fruits and vegetables are the hexoses, glucose and fructose (Fig. 9.1). Other minor monosaccharides include ...
According to their chain length, monosaccharides fall into several categories, the more nutritionally important being the pentoses (5-carbon atom skeleton), e.g., ribose, and the hexoses (6-carbon atom skeleton), e.g., glucose. The presence of asymmetrical carbons in monosaccharides with ...
carbons. The difference betweengalactoseand fructose is mainly defined based on the attachment of asymmetric carbons. The placement of asymmetric carbon makes a slight difference and gives definite shape andbinding activitiesand subsequently different behaviors. In an aqueous solution, all the five-carbon...
Monosaccharidescontainhydroxyl groupsand react with acids to form a variety of esters. Thephosphate estersplay a main role incarbohydrate metabolism. For example, the first step of glycolysis involves the production of the glucose-6-phosphate ester in a reaction catalyzed by the enzymeglucokinasein th...
