What is the difference between GHK-Cu and NAD+?
GHK-Cu is a copper(II) complex of the tripeptide GHK, first identified in human plasma, and widely studied in skin-biology, cosmetic-science and wound-model research (peptide-copper complex, MW about 402.92 g/mol).
Which is heavier, GHK-Cu or NAD+?
GHK-Cu has a molecular weight of about 402.92 g/mol and NAD+ about 663.4 g/mol (PubChem), so NAD+ is heavier by 260.5 g/mol, a ratio of 1.65. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 1,507.4 nmol for NAD+.
How many mg of NAD+ are equimolar to 1 mg of GHK-Cu?
1 mg of GHK-Cu (MW 402.92) is 2,481.9 nmol. The same number of moles of NAD+ (MW 663.4) weighs 1.646 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and NAD+
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and NAD+ as C21H27N7O14P2 (663.4 g/mol). GHK-Cu is a peptide-copper complex; NAD+ is a dinucleotide coenzyme (not a peptide). These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHK-Cu equals how many mg of NAD+ in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of NAD+ (MW 663.4) would weigh 8.232 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 50 mg vial of GHK-Cu equals how many mg of NAD+ in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of NAD+ (MW 663.4) would weigh 82.324 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHK-Cu equals how many mg of NAD+ in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of NAD+ (MW 663.4) would weigh 16.465 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of GHK-Cu equals how many mg of NAD+ in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of NAD+ (MW 663.4) would weigh 32.93 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of GHK-Cu equals how many mg of NAD+ in moles?
30 mg of GHK-Cu (MW 402.92) is 74.456 µmol. The same amount of NAD+ (MW 663.4) would weigh 49.394 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 100 mg vial of GHK-Cu equals how many mg of NAD+ in moles?
