Question

Which of the following statements describe(s) the peptide bond? (More than one answer may be correct.)

A. It is the only covalent bond between amino acids in polypeptides.
B. It is a substituted amide linkage.
C. It is formed in a condensation reaction.
D. It is formed in an exergonic reaction.
E. It is unstable under physiological conditions.

Answer 1

Peptide bonds are covalent bonds that form between amino acids in a condensation reaction. They are stable under physiological conditions and are responsible for linking amino acids together to form polypeptides.

Step-by-step explanation:

Peptide bonds are covalent bonds that form between two amino acids during a condensation synthesis reaction. They are a unique type of bond called a peptide bond, which is a substituted amide linkage. Peptide bonds are stable under physiological conditions and are responsible for linking amino acids together to form polypeptides.
