Detailed explanation-1: -D. Inulin. Hint: In homopolysaccharides, all sugar components are the same. This variety includes cellulose, starch, glycogen, and para-mil.
Detailed explanation-2: -Inulin is a heteropolymer made of (2, 1) linked glucosyl and repetitive fructosyl units. Hence, Inulin is not a polymer of just glucose.
Detailed explanation-3: -Homopolysaccharides or homoglycans are those complex carbohydrates which are formed by polymerisation of only one type of monosaccharide monomers. For example, starch, glycogen, inulin, cellulose, chitin, etc. Agar, pectin, hyaluronic acid, heparin, etc., are hetero polysaccharides.
Detailed explanation-4: -Some examples of heteropolysaccharides:i) Peptidoglycans, ii) Agarose, and iii) Glycosaminoglycans (GAGs). Peptidoglycan (murein) is a part of the bacterial cell wall which is found on the outside of almost all of the bacteria’s cytoplasmic membrane.
