Peptide Chemistry

Peptides are widely present in nature and in living organisms. They are a type of natural substance composed of two or more amino acids connected by peptide bonds. They are also the product of incomplete hydrolysis of proteins. So far, a wide variety of peptides have been found in organisms, and they play an important role in participating in and regulating life activities in the body. According to the number of amino acids, they can be divided into oligopeptides (2-1 amino acids) and polypeptides (1-1 amino acids).
