The carbohydrate glycogen
A. is a polysaccharide.
B. has a structure resembling amylose.
C. is also found in yeast and fungi.
D. is known as animal starch.
Choose the correct statements from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A, C and D only
Glycogen is the storage polysaccharide of animals, built from α-D-glucose units. The point that decides the statements is its branching: chains of C1–C4 glycosidic links branch through C1–C6 links, even more than in amylopectin.
(A) is a polysaccharide. — Correct. Glycogen is made of a very large number of glucose units.
(B) has a structure resembling amylose. — Incorrect. Amylose is an unbranched chain with only C1–C4 links. Glycogen is highly branched, so its structure resembles amylopectin, not amylose.
(C) is also found in yeast and fungi. — Correct. Besides animals, glycogen also occurs in yeast and fungi.
(D) is known as animal starch. — Correct. Its structure resembles the amylopectin part of starch and it plays the storage role of starch in animals, so it is called animal starch.
