Palmitoyl pentapeptide-4 (Pal-Lys-Thr-Thr-Lys-Ser = Pal-KTTKS) contains 5 amino acids linked to a 16-carbon aliphatic chain for improving the penetration of the molecule through the lipid structures of the skin. It is a matrikine. [1]
The reverse reaction in mammalian cells is catalyzed by acyl-protein thioesterases (APTs) in the cytosol and palmitoyl protein thioesterases in lysosomes. Because palmitoylation is a dynamic, post-translational process , it is believed to be employed by the cell to alter the subcellular localization, protein–protein interactions, or binding ...
A tripeptide (example Val-Gly-Ala) with green marked amino end (L-Valine) and blue marked carboxyl end (L-Alanine) A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. [1] As for proteins, the function of peptides is determined by the constituent amino acids and their sequence.

[5] Amino acids that have been incorporated into peptides are termed residues. A water molecule is released during formation of each amide bond. [6] All peptides except cyclic peptides have an N-terminal (amine group) and C-terminal (carboxyl group) residue at the end of the peptide (as shown for the tetrapeptide in the image).
But there is a range of ultra-processed foods. “Some ultra-processed foods, like protein powders or cereal, could be part of a healthy diet,” says Dena Champion, RDN, a dietitian at The Ohio ...
Glutathione - A tripeptide with many roles in cells. It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides.
