Unlike many peptides that act through a single well-defined receptor, GHK-Cu exerts its biological effects through multiple mechanisms including direct stimulation of collagen and glycosaminoglycan synthesis, activation of antioxidant enzymes, modulation of metalloproteinase activity, promotion of angiogenesis, and broad regulation of gene expression across hundreds of genes involved in tissue repair, inflammation, and cellular protection
Therefore, temp-only the GSSG is detected by measuring the absorption (max = 412 nm) of DTNB (5,5 Edithiobis (2-nitrobenzoic acid) using the enzymatic recycling system
First, hyperhomocysteinemia detected only in the fasting state (approximately 23% of patients), which might mainly result from an inhibition of the homocysteine remethylation pathway (folate, cobalamin, or functional methionine synthase deficiencies or thermolabile MTHFR mutation), and which increases the cardiovascular risk 1.6-fold
