How we scored it
Three amino acids (glycine, histidine, lysine) joined by amide bonds; all fermentation-derived, coupling reagents leave no mass. Whole molecule = 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Manufactured by solid-phase peptide synthesis from fermentation-derived glycine, histidine and lysine. Synthesis reagents and protecting groups leave no mass in the final peptide.
In plain English
A skin-conditioning peptide made from three amino acids (glycine, histidine and lysine), the same sequence found in the body's own copper-binding peptide. It is manufactured by joining fermentation-derived amino acids together.
CosIng definition: Tripeptide-1 is a synthetic peptide containing glycine, histidine, and lysine
Structure
(2S)-6-amino-2-[[(2S)-2-[(2-aminoacetyl)amino]-3-(1H-imidazol-5-yl)propanoyl]amino]hexanoic acid
