From the X-ray crystal structure of model peptides (DAHK) it is known that Cu(II) ion in NTS (DAH) is equatorially coordinated by N-terminal amine, two deprotonated peptide bond nitrogens and imidazole of His-3, whereas one apical coordination site is occupied with water 35
GHK-Cu is a copper-binding tripeptide complex referenced in scientific literature for its role in cellular signaling, extracellular matrix research, and peptide-metal interaction studies
These central nervous system effects contribute to appetite suppression (which is therapeutically beneficial) but can also produce nausea as a side effect
Sleep, Hunger Hormones, and Weight Loss Research consistently shows that sleep deprivation increases ghrelin (the hunger hormone) and decreases leptin (the satiety hormone), creating a biochemical environment that drives overeating
