What is the difference between GHK-Cu and SLU-PP-332?
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 SLU-PP-332?
GHK-Cu has a molecular weight of about 402.92 g/mol and SLU-PP-332 about 290.3 g/mol (PubChem), so GHK-Cu is heavier by 112.6 g/mol, a ratio of 1.39. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 3,444.7 nmol for SLU-PP-332.
How many mg of SLU-PP-332 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 SLU-PP-332 (MW 290.3) weighs 0.7205 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and SLU-PP-332
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and SLU-PP-332 as C18H14N2O2 (290.3 g/mol). GHK-Cu is a peptide-copper complex; SLU-PP-332 is a small molecule (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 SLU-PP-332 in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of SLU-PP-332 (MW 290.3) would weigh 3.602 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 SLU-PP-332 in moles?
