tripeptide
Three linked aminos
A tripeptide is a molecule consisting of three amino acids linked by peptide bonds.
Tripeptides are among the simplest peptide chains, falling between dipeptides (two amino acids) and longer polypeptides.
Some occur naturally in the body, like glutathione, which plays a role in cellular defense against oxidative damage.
