Tripeptide-1 Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Tripeptide-1 is a small peptide composed of three amino acids  (glycine-histidine-lysine or GHK) and is known for type I collagen fragments. When collagen fragment peptides (GHK) are added, it may mistakenly lead the skin to think that collagen has been broken down, resulting in more collagen. Therefore, tripeptide-1 is believed to stimulate collagen production in the skin. More collagen will reduce wrinkles on the face, which will improve the condition of the skin.

  Liver Cell Growth Factor

• Verwenden

  Gly-His-Lys acetate salt has been used:
  
  • individually or as a complex with copper to test its effect on cytokines production in the human normal fibroblasts cell lines
  • as a model peptide in N,N-dimethyl-N-methacryloxyethyl-N-(3-sulfopropyl)ammonium betaine based capillary electrophoresis separation studies
  • as a component of Coon′s modified Ham′s F-12 medium for culturing Fischer rat thyroid follicular cell line, FRTL-5
  
  

• Allgemeine Beschreibung

  Gly-His-Lys is a tripeptide present at ～200ng/ml in association with α-globulin and albumin, in human blood plasma.

• Biochem/physiol Actions

  Gly-His-Lys (GHK) acetate salt displays affinity towards copper(II) ions. This property enables GHK to modulate the copper intake into cells. GHK is also involved in quenching toxic by-products generated by lipid peroxidation.

• in vitro

  In an enzyme assay, the liver growth factor, Tripeptide-1, was hydrolyzed by an aminotripeptidase purified from rat brain cytosol[1].

• in vivo

  Tripeptide-1 (1% in saline; dose = 10 mg/kg) was injected into the tail vein of male rats (number not specified). Blood samples were collected prior to dosing and for up to 60 minutes post-dosing. Plasma concentration-time profiles of Tripeptide-1 and its l-histidyl-l-lysine metabolite indicated that neither was detected in predose plasma samples. However, after intravenous (IV) injection, Tripeptide-1 was rapidly degraded to l histidyl-l-lysine, rapidly eliminated from circulating blood. It has been reported that Tripeptide-1 is unstable in human plasma and is rapidly degraded by aminopeptidases[1].
