Incorrect Statement about Amino Acids:




a) There are 20 naturally occurring amino acids:
This statement is correct. There are 20 standard amino acids that are naturally occurring and are used by the body to build proteins. These amino acids differ in their side chains, which give each amino acid its unique properties.

b) Amino acids are classified as acidic, basic or neutral based on the relative number of amino and carboxylic groups:
This statement is also correct. Amino acids can be classified as acidic, basic, or neutral depending on the nature of their side chains. Acidic amino acids have a carboxylic acid group in their side chains, basic amino acids have an amino group, and neutral amino acids have side chains that are neither acidic nor basic.

c) All the amino acids are chiral:
This statement is incorrect. While most of the naturally occurring amino acids are chiral and exist in the L-configuration, there are exceptions. Glycine, for example, is achiral because its side chain is a hydrogen atom.

d) Amino acids are classified as essential amino acids and non-essential based on whether they are synthesized in the body or not:
This statement is correct. Amino acids are classified as essential or non-essential based on whether the body can synthesize them on its own. Essential amino acids must be obtained from the diet since the body cannot produce them, while non-essential amino acids can be synthesized by the body.
