Detailed explanation-1: -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-2: -A peptide bond, also referred to as an amide bond, is formed between the -nitrogen atom of one amino acid and the carbonyl carbon of a second (diagrammed below). So-called isopeptide bonds refer to amide bonds between sidechain amines or carbonyl carbons on the side chain rather than -amine or -carbonyl.
Detailed explanation-3: -Peptide bond: A covalent bond joining the -amino group of one amino acid to the carboxyl group of another with the loss of a water molecule.
Detailed explanation-4: -… A peptide is a short chain of amino acids (typically 2 to 50) linked by chemical bonds (called peptide bonds). A longer chain of linked amino acids (51 or more) is a polypeptide.
