Amino Acid Sequence

Gly-His-Lys

General description

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

Application

Gly-His-Lys (GHK) has been used for the preparation of post-operative intra-articular injection of GHK-Cu (copper).
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

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.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

After anterior cruciate ligament reconstruction (ACLR), the biological healing of the graft is a rate-limiting step which can contribute to graft failure. The tripeptide-copper complex glycyl-L-histidyl-L-lysine-Cu(II) (GHK-Cu) is a well-known activator of tissue remodeling. We investigated whether GHK-Cu can improve

A novel capillary with covalently bonded zwitterionic surface modification was prepared by photograft polymerization of the zwitterionic monomer N,N-dimethyl-N-methacryloxyethyl-N-(3-sulfopropyl)ammonium betaine, onto the inner surface of a UV-transparent fused-silica capillary. Although the zwitterionic moieties in the resulting polymeric "tentacles" comprise both

Isolation and purification of growth-modulating peptides from biological sources is often accompanied by excessive losses of bioactive material. During the isolation of a growth-modulating tripeptide glycylhistidyllysine (GHL) from human plasma, copper and iron were found to co-isolate with the peptide.
