BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Peptides are generally considered to be short chains of two or more amino acids. Meanwhile, proteins are long molecules made up of multiple peptide subunits, and are also known as polypeptides.

Detailed explanation-2: -Definition. 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.

Detailed explanation-3: -A peptide bond forms when the amino group of one amino acid bonds to the carboxyl group of another amino acid. A peptide is two or more amino acids joined together by peptide bonds, and a polypeptide is a chain of many amino acids. A protein contains one or more polypeptides.

Detailed explanation-4: -Quaternary structure However, some proteins are made up of multiple polypeptide chains, also known as subunits. When these subunits come together, they give the protein its quaternary structure.
