Question

Which among the following statements is incorrect about classification of protein?

(a) Fibrous proteins result when long peptide chains run parallel and are held by hydrogen and sulphide linkages

(b) Globular structures result when chain of polypeptide coil around themselves to form a globe like structure

(c) Linear structure of amino acids in a polypeptide is called primary structure

(d) Collagen is an example of globular protein

This question was posed to me during an online interview.

The above asked question is from Biomolecules-2 in division Biomolecules of Biology – Class 11

Answer 1

The correct option is (d) Collagen is an example of globular protein

Explanation: Fibrous proteins result when long peptide chains run parallel and are held by hydrogen and sulphide linkages. Globular structures result when chain of polypeptide coil around themselves to form a globe like structure. Linear structure of amino acids in a polypeptide is called primary structure. Collagen is an example of fibrous protein.
