BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glucose is the most abundant monosaccharide. Galactose, mannose, fructose and ribose are also of major biological importance.

Detailed explanation-2: -The hexose D-glucose is the most abundant monosaccharide in nature. Other very common and abundant hexose monosaccharides are galactose, used to make the disaccharide milk sugar lactose, and the fruit sugar fructose.

Detailed explanation-3: -d-Glucose, considering all of its combined forms, is the most abundant monosaccharide that naturally occurs in nature [13]. The most abundant ketose is d-arabino-hexulose, known more commonly by its trivial name, d-fructose [2].

Detailed explanation-4: -Presumably, glucose is the most abundant natural monosaccharide because it is less glycated with proteins than other monosaccharides.

Detailed explanation-5: -Glucose is the most abundant monosaccharide found in nature, while cellulose is the most abundant polysaccharide.
