Peptides are a group of biologically active substances that are involved in various cellular functions of organisms. Peptides are often used in functional analysis, antibody research, vaccine research and especially in the field of drug research and development. Peptides have a variety of biological functions, such as, anti-thrombosis, anti-hypertension, antibacteria, antivirus, anticancer and antioxidation, immunoregulation, and cholesterol-lowering effects.
