(b) Polysaccharides mainly act as the food storage or structural materials

(d) Amylopectin has α-1, 4-linkage and 1, 6-glycosidic linkage

I got this question by my school principal while I was bunking the class.

Asked question is from Biomolecules-1 topic in chapter Biomolecules of Biology – Class 11

Answer 1

The correct choice is (c) Starch comprises of two forms, namely, amylose (water insoluble) and amylopectin (water soluble)

The best I can explain: Cellulose can’t be digested by mammals unless they contain microbes that digest cellulose in their gut. Polysaccharides mainly act as the food storage or structural materials. Starch comprises of two forms, namely, amylose (water soluble) and amylopectin (water insoluble). Amylopectin has α-1, 4 and 1, 6-glycosidic linkage.
