What are Peptides?

Peptides are two or more amino acids connected by a peptide chain, between large molecule proteins and small molecule amino acids, and are functional nutrients essential for the body to accomplish various complex physiological activities. Peptides, as basic materials, constitute active substances in the body such as enzymes, hormones, antibodies, interneurons, etc., and regulate the physiological functions of various systems and cells, which are irreplaceable and important for cellular activity, functional activities, and the existence of life. Peptides can be categorized according to molecular weight size:

  • Small peptides - Small peptides, also called small molecule peptides, are highly active peptides consisting of only 2 to 4 amino acids.
  • Oligopeptides - Oligopeptides are peptides consisting of 2-10 amino acids, with molecular weights generally below 1000 daltons.
  • Polypeptides - Polypeptides refer to peptides consisting of 10-50 amino acids.
  • Proteins - Proteins generally refer to peptides consisting of more than 51 amino acids.

What is a Peptide Drug?

Peptide drugs mainly include peptide vaccines, anti-tumor peptides, anti-viral peptides, peptide-directed drugs, cytokine-mimicking peptides, antimicrobial active peptides, diagnostic peptides, as well as other small peptides for medicinal purposes. Because of their wide indications, high safety, and remarkable efficacy, peptide drugs can be widely used in the prevention, diagnosis, and treatment of tumors, cardiovascular and cerebrovascular diseases, hepatitis, diabetes, AIDS, and other diseases.
