The peptide bond joining amino acids into proteins is a specific example of the ________ bond.

Question

Quizplus · Accepted Answer

The peptide bond is formed between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid, creating an amide bond (-CO-NH-) between them. Therefore, the peptide bond is a specific example of an amide bond. Choice B (carbonyl) and C (ester) are not correct because they do not involve the amino group. Choice D (glycosidic) is incorrect because it involves the bonding of monosaccharides in carbohydrates, not amino acids in proteins. Choice E (hydrogen) is incorrect because it involves the weak interaction between hydrogen atoms and electronegative atoms, such as nitrogen or oxygen, not the covalent bonding between two amino acids.
