Peptides are short chains of amino acids that are the building blocks of proteins. They play a crucial role in various biological functions in the body, such as hormone regulation, immune system function, and cell signaling. Peptides are smaller than proteins and are made up of fewer amino acids, typically ranging from 2 to 50 amino acids in length.

Overall, peptides are essential molecules that play a critical role in the functioning of the human body. Research into the potential uses of peptides continues to expand, offering new possibilities for improving health and well-being.
