BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A peptide is two or more amino acids joined together by peptide bonds; a polypeptide is a chain of many amino acids; and a protein contains one or more polypeptides. Therefore, proteins are long chains of amino acids held together by peptide bonds.

Detailed explanation-2: -And just to make it a little more complicated, you will often hear scientists refer to polypeptides – a chain of 10 or more amino acids.

Detailed explanation-3: -When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein.

Detailed explanation-4: -To form polypeptides and proteins, amino acids are joined together by peptide bonds, in which the amino or NH2 of one amino acid bonds to the carboxyl (acid) or COOH group of another amino acid.
