Question

Which among the following is incorrect about amino acids?

(a) Amino acids are those that contain an amine group and a carboxylic group

(b) Base on the position of amino group with respect to the carboxylic group, amino groups are classified as α-, β-, γ-, δ- amino acids

(c) Proteins on hydrolysis produce α-, β-, γ-, δ- amino acids

(d) Amino acids are usually represented by a three letter symbol or a one letter convention

This question was posed to me during a job interview.

This intriguing question originated from Biomolecules-2 topic in section Biomolecules of Biology – Class 11

Answer 1

Correct answer is (c) Proteins on hydrolysis produce α-, β-, γ-, δ- amino acids

The explanation is: Amino acids are those that contain an amine group and a carboxylic group. Base on the position of amino group with respect to the carboxylic group, amino groups are classified as α-, β-, γ-, δ- amino acids. Proteins on hydrolysis produce only α-amino acids.
