What is a peptide?

What is a peptide? A peptide is the amino group of one amino acid and the carboxyl group of another amino acid, which are condensed to form a peptide, forming this acyl amino group. It is called a peptide bond in protein chemistry. Amino acids have the smallest molecule, while proteins have the largest molecular weight. After dehydration, two or more amino acids form several peptide bonds, forming a peptide. Multiple peptides then fold multiple groups, ultimately forming a protein molecule. Proteins are sometimes referred to as peptides.

As the name suggests, peptides are actually several proteins and amino acids that connect to form a functional structure. They can be divided into functions such as antihypertensive peptides, antioxidant peptides, cholesterol lowering peptides, etc. They are closely related to the nutrients in our nutrition, hormones, enzymes, immune regulation, antibacterial, antiviral, antioxidant, and many other functions of the body. Peptides can be broadly divided into two categories: one is called peptide drugs, and the other is called peptide health products. Traditional peptide drugs mainly consist of peptide hormones, and we now have some peptide drugs for improving immunity. In recent years, The development of peptide drugs has made significant progress in various fields of diseases.
