Glycogen is a homonpolymer made up of

Options

A. glucose units
B. galactose units
C. ribose units
D. amino acids

Answer

A

Explanation

Glycogen is the storage polysaccharide present in animals. Glycogen consist of glucose molecule linked together with a (1 `rarr` 4) linkages with a (1 `rarr 6) branch points occurring every 8-12 residues.
Galactose, on the other hand is a monosaccharide, and combines with glucose through condensation reaction, resulting in the formation of disaccharide, lactose. Ribose is a pentose monosaccharide which has all hydroxyl group on the same side in fisher projection. It forms a part of backbone in RNA and DNA. Amino acids are the monomers of proteins.
