They are also the basis of numerous medicines.



Peptides are mainly categorised in three extraordinary methods:


According to how many amino acids make up the chain: Oligopeptides have few amino acids, while polypeptides are longer chains—commonly between 20 to 50 amino acids. Dipeptides, tripeptides, and tetrapeptides have , three, and four amino acids respectively.

According to their source, whether plant or animal

According to their functions in the human body

Functions within the Body

Peptides play many roles inside the human frame. Some peptides and their functions include:


Vasopressin (antidiuretic hormone): This is a peptide hormone that secreted inside the hypothalamus— a small portion of the mind that’s placed at the bottom of the brain. Vasopressin has a couple of features.
