Peptide Bond, Peptide Chain and Proteins
- Peptide chain consists of two or more amino acids joined together via a covalent bond.
- This covalent bond between two amino acid is called a peptide bond.
- A peptide bond is formed when the carboxyl group of one amino acid and the amino group of the other amino acid combine, releasing a molecule of water.
- The two amino acids connected via a peptide bond are called dipeptide.
- When 12-20 amino acids are joined, an oligopeptide is formed.
- When more than twenty amino acids are linked, a polypeptide is formed.
- One or more polypeptide combine together to form proteins.
-
A dipeptide has two amino acids that are linked via one peptide bond.
