Proteins
The peptide bond in proteins is formed by a condensation reaction between:
Select the correct option:
Solution
The amino group of one amino acid and the carboxyl group of another
A peptide bond (—CO—NH—) is formed when the α-amino group (—NH₂) of one amino acid reacts with the α-carboxyl group (—COOH) of an adjacent amino acid, releasing one molecule of water (condensation). This amide linkage is the fundamental covalent bond that links amino acid residues in a polypeptide chain.
