Acquisition of 1 H-NMR spectra and metabolic profiling The lyophilized metabolic extracts were suspended in 0.6 ml of deuterated water (Cambridge Isotope Laboratories Inc., Tewksbury, MA, USA) containing phosphate buffer (100 mM) and TSP (3-3-(trimethylsilyl)-2,2,3,3-tetradeuteropropionic acid or TMSP- d 4 , Cambridge Isotope Laboratories) (0.5 mM) and inserted into a 5 mm NMR tube for immediate acquisition
The most common effects are mild warmth during the infusion, a metallic taste, or minor bruising at the IV site
GSH Insufficiency and Diabetic Complications Glutathione (GSH), a tripeptide composed of glutamine, cysteine, and glycine, serves as a key antioxidant that supports cellular detoxification and protection
or D or L norleucine, , lysine, arginine, norvaline, ornithine, or S-benzyl cysteine II = a D or L cysteine, phenyalanine, aspartic acid, glutamic acid, serine, tyrosine, glycine, homocysteine, homoserine or homophenylalanine amino acid residue
GHK-Cu has a variety of roles in the human body including, but not limited to promoting activation of wound healing, attracting immune cells, antioxidant and anti-inflammatory effects, and stimulating collagen and glycosaminoglycan synthesis to help reduce wrinkles and fine lines in skin
