Question

When sugars polymerize in long chains, they may form any of the following except:

Answer 1

Answer:

The correct answer is- proteins

Explanation:

Sugar polymerize to form several polymers like glycogen, cellulose, starch, chitin. Glycogen is a sugar polymer which acts as a reserve energy source in muscles in animals.

Cellulose is a sugar polymer that makes the cell wall of plant cell and starch is a sugar polymer that acts as energy storage form in plant cells. Protein can not be formed by sugar polymerization in long-chain because sugar is not the monomeric unit of protein and the monomeric unit of protein is amino-acid.

Therefore amino acid is required to be polymerized to form proteins.

Answer 2

When sugars polymerize in long chains, they may form any of the following except PROTEIN.
