Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Inulin is a ____ which is a collection of ____ polymers.
A
Heteropolysaccharide, fructose and galactose
B
Heteropolysaccharide, fructose and mannose
C
Homopolysaccharide, fructose
D
Homopolysaccharide, mannose
E
Homopolysaccharide, ribose
Explanation: 

Detailed explanation-1: -Inulin is a polymer composed of fructose monomers linked via -(2-1)-d-frutosyl fructose bonds. It is indigestible in human small intestine due to presence of -configuration of C-2 and can be fermented by intestinal microflora in large intestine [70].

Detailed explanation-2: -Homopolysaccharides or homoglycans are those complex carbohydrates which are formed by polymerization of only one type of monosaccharide monomers. For example, starch, glycogen, inulin, cellulose, chitin, etc.

Detailed explanation-3: -Fructans are polymers of fructose linked by -(1 → 2) bonds. The best-known example is inulin with 3–60 fructose units per chain.

Detailed explanation-4: -Various homopolysaccharides (HoPSs) can be produced by bacteria: -and -glucans, -fructans and -galactans, which are polymers of glucose, fructose and galactose, respectively.
