BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The other naturally occurring hexoses of physiological importance are galactose and mannose, which are aldohexoses, and fructose which is the only commonly occurring ketohexose.

Detailed explanation-2: -Mannose is a hexose monosaccharide that belongs to the group of aldoses. As an aldose, mannose has an aldehyde as a functional group. Mannose is a stereoisomer of glucose. In particular, it is a C-2 epimer of glucose.

Detailed explanation-3: -The three main monosaccharides that we consume are fructose, galactose and glucose. These monosaccharides combine in various pairs to form the three disaccharides that are most important in human nutrition: lactose, maltose and sucrose. The monosaccharide glucose is the common thread in each of these disaccharides.

Detailed explanation-4: -1 Monosaccharides. Monosaccharides are the simplest carbohydrates; most of them are sugars. Monosaccharides may have between three and eight carbon atoms, but only those with five carbons (pentoses) and six carbons (hexoses) are common.
