Peptide

A general term for molecules consisting of short chains of amino acids. It is said to be derived from the Greek word “πεπτος“(digestible). A peptide with two amino acids is called a “dipeptide”, a peptide with three amino acids is called a “tripeptide”, a peptide with 10 or fewer amino acids is called an “oligopeptide”, and a peptide with many amino acids linked together is called a “polypeptide”.
