Endogenous Antioxidant Peptides:
Beyond exogenous sources, the body naturally produces its own antioxidant peptides. Glutathione, a tripeptide known as $\gamma$-l-glutamyl-l-cysteinyl-glycine, is a prime example of an endogenous antioxidant synthesized in both animals and plants. Other naturally occurring endogenous antioxidant peptides include carnosine, anserine, and ophidine. Cyclo(His-Pro) and the human tripeptide GHK (Gly-His-Lys) are also recognized for their antioxidant roles.
The antioxidant activity of a peptide is often influenced by its amino acid composition and sequence.Inflammatory Peptide - an overview | ScienceDirect Topics Hydrophobic amino acid residues, such as Pro, Tyr, Trp, Met, Gln, and Ala, are frequently found in antioxidative peptides and contribute to their radical-scavenging mechanisms. For example, peptides rich in tyrosine (Tyr) have shown significant antioxidant activity.
