Question
Chapter 2, Problem 12P
Interpretation Introduction
Interpretation:
The meaning of the term polypeptide backbone should be determined.
Concept introduction:
A peptide bond exists between the two amino acids. During the formation of a peptide bond, a molecule of water is released. The carboxyl group of one amino acid gets linked with the amino group of the other amino acid. Polypeptides and proteins are the chains formed by the amino acids.
