What is the N-Acetyl-beta-alanyl-L-histidyl-L-seryl-L-histidine?

N-Acetyl-beta-alanyl-L-histidyl-L-seryl-L-histidine is , while it's Molecular Formula is C20H28N8O7. Acetyl tetrapeptide-5 is known as eye peptide and eye silk peptide. The molecular weight of acetyltetrapeptide-5 is 492.5 and the amino acid sequence is Ac- βAla-His-Ser-His-OH, the molecular formula is C20H28N8O7. The influence of saccharification in the body and the increase of ocular vascular osmotic pressure will make the eye skin form dark circles and edema. Some studies have proved that acetyltetrapeptide-5 can reduce edema by changing the microcirculation of regional skin and the osmotic pressure of liquid, so as to effectively eliminate edema, eye bags and dark circles.
