Detailed explanation-1: -Peptide bonds are amide bonds between the -carboxyl group of one amino acid and the -amino group of another (Fig. 3-1). The result is a planar structure that is stabilized by resonance between the -carboxyl and -amino groups.
Detailed explanation-2: -Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
Detailed explanation-3: -A peptide bond is a chemical covalent bond that joins amino acids together to form proteins. A peptide bond occurs between a carbon atom of one amino acid with a nitrogen atom of the other amino acid by removing a hydroxyl group and a hydrogen atom to form a molecule of water.
