BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The monosaccharides are water soluble but are insoluble in non-polar solvents. Glyceraldehyde and glycerone are considered to be the simplest aldose and ketose respectively (Figure 3.1).

Detailed explanation-2: -Monosaccharides are quite soluble in water because of the numerous OH groups that readily engage in hydrogen bonding with water.

Detailed explanation-3: -Monosaccharides such as glucose and fructose are crystalline solids at room temperature, but they are quite soluble in water, each molecule having several OH groups that readily engage in hydrogen bonding.

Detailed explanation-4: -Most polysaccharides (sugar polymers) are far less soluble in water than their monomers (simple sugars). This happens because the polymer linkage between sugars ties up two of the sugar’s reactive groups, which prevents those two groups from interacting with water.
