A) Starch is a polymer of a -glucose
B) Starch is made up of amylase and amylopectin
C) Amylase in linear structure consisting of several glucose residues joined by 1, 4-glycosidic linkage
D) Amylopectin is a straight chain with several glucose residues joined only by 1, 4-glycosidic linkages
Correct Answer: D
Solution :
Starch is a homopolysaccharides, which is a polymer of \[\alpha \]- glucose. It is made up of two component amylase and amylopectin amylase is a linear structure consisting of several glucose resides joined only by \[\alpha \], 1-4 glycosidic bonds (contain 200-1000 resides) while amylopectin is straight outer chain with short chain of glucose unit (25-35) linked by \[\alpha \]-1,4 glycosidic linkages.
