Types of peptides

Peptides are only those with a molecular weight range of 50-5000. A peptide with a molecular weight range of 5000 to 10000 is called a large peptide. Peptides with a molecular weight range of 50-2000 are called small peptides, oligopeptides, oligopeptides, and also known as small molecule active peptides. Biologists refer to peptides as "amino acid chains" and collectively refer to small molecule active peptides as "biologically active peptides". Common peptides include dipeptides, tripeptides, and even polypeptides, while 2-10 peptides belong to oligopeptides and 10-50 peptides belong to peptides. Generally, those with less than ten peptides are more useful in medicine and commerce.
