Which of the following is a heteropolymer ?

Options

A. Cellulose
B. Peptidoglycan
C. Starch
D. Glycogen

Answer

B

Explanation

Homopolysaccharids or homogycans are those complex carbohydrates which are formed by polymerisation of only one type of monosaccharide monomers. For example, starch, glycogen and cellulose are composed of a single type of monosaccharide called glucose. similarly, chitin is composed of monomer units of N- acetylglucosamine. Depending upon monosaccharide unit involved, polysaccharide is called glucan (made of glucose ), fructan (made of fructose), xylan (having xylose) etc.
Heteropolysaccharides or heteroglycans are those complex carbohydrates which are produced by condensation of two or more types of monosaccharide derivatives, `e.g, agar, peptidoglycan, glycosaminoglycans, etc.
