A peptide bond ________.
A) forms between the functional R-groups of different amino acids
B) forms between the central carbon and the amino R-group of a single amino acid
C) forms the primary structure of proteins
D) does not play a role in maintaining the tertiary structure of proteins

Question

Quizplus · Accepted Answer

A peptide bond forms between the carboxyl group of one amino acid and the amino group of another amino acid, forming the primary structure of proteins. Choice A and B are incorrect because peptide bonds do not involve functional R-groups or the central carbon of an amino acid. Choice D is incorrect because peptide bonds do play a crucial role in maintaining the tertiary structure of proteins by linking amino acid residues together in a specific sequence.
