Peptide Bond

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

A peptide or amide (-CO-NH-) bond is formed by the linking of the carboxyl group of one amino acid with the amino group of another with the loss of a water molecule. In this bond, the oxygen atom of the carbonyl group is in the trans position with respect to the hydrogen on the nitrogen atom and all of these four atoms are planar due to resonance. This bond has a partially (40%) double-bond character, and the half-life for the hydrolysis of peptide bonds is 350-600 years at room temperature and at pH 4-8. The selective hydrolysis of the peptide bond of peptides and proteins is required in a wide range of biological, biotechnological, and industrial applications.
