Question
How is tripeptide formed?
Solution
b. The reaction of the COOH group of one amino acid molecule and NH2 group of the neighbouring amino acid molecule forms peptide having -CO-NH- linkage by
elimination of water
The dipeptide formed reacts with another molecule of amino acid to form tripeptide
