What is the difference between GHK-Cu and KPV?
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 KPV?
GHK-Cu has a molecular weight of about 402.92 g/mol and KPV about 342.43 g/mol (PubChem), so GHK-Cu is heavier by 60.49 g/mol, a ratio of 1.18. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 2,920.3 nmol for KPV.
How many mg of KPV 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 KPV (MW 342.43) weighs 0.8499 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and KPV
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and KPV as C16H30N4O4 (342.43 g/mol). GHK-Cu is a peptide-copper complex; KPV is 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 KPV in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of KPV (MW 342.43) would weigh 4.249 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
