D)amino,carboxylate,peptide

Question

Quizplus · Accepted Answer

A dipeptide forms when the carboxylate group (-COOH) of one amino acid reacts with the amino group (-NH2) of another amino acid to form a peptide bond (-CO-NH-) between the two amino acids. Therefore, the correct functional groups involved in dipeptide formation are amino and carboxylate, and the correct bond formed is a peptide bond. Choice A is incorrect because it lists double instead of peptide bond. Choices B and C are incorrect because they mix up the functional groups involved in peptide bond formation.
