Show the formation of a peptide bond with an equation. (OR) What is a peptide bond? Illustrate the formation of a peptide bond in glycin alanine.

Explanation

(i) The bond formed between two amino acids by the elimination of a water molecule is called peptide linkage or bond,
(ii) The amino group of one amino acid and a carboxyl group of other amino acid undergoes condensation to remove a water molecule and it results in the formation of bond.

(iii) The product formed by linking amino acid molecules through peptide linkages is called a peptide
(iv) In peptide formation.the two different amino acid molecules may react in one of the two ways.
