Which among the following is incorrect about amino acids?(a) There are 20 naturally occurring amino acids(b) All the amino acids are chiral(c) Amino acids are classified as acidic, basic or neutral based on the relative number of amino and carboxylic groups(d) Amino acids are classified as essential amino acids and non-essential based on whether they are synthesized in the body or notThis question was addressed to me in an online interview.I'd like to ask this question from Biomolecules-2 topic in portion Biomolecules of Biology – Class 11
Answer» The correct choice is (b) All the AMINO acids are CHIRAL Easiest explanation: There are 20 naturally occurring amino acids. All the amino acids EXCEPT glycine are chiral. Amino acids are classified as acidic, basic or neutral based on the relative number of amino and CARBOXYLIC groups. Amino acids are classified as essential amino acids and non-essential based on whether they are SYNTHESIZED in the body or not.
