What is the difference between GHK-Cu and SNAP-8?
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 SNAP-8?
GHK-Cu has a molecular weight of about 402.92 g/mol and SNAP-8 about 1075.2 g/mol (PubChem), so SNAP-8 is heavier by 672.3 g/mol, a ratio of 2.67. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 930.1 nmol for SNAP-8.
How many mg of SNAP-8 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 SNAP-8 (MW 1075.2) weighs 2.669 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and SNAP-8
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and SNAP-8 as C41H70N16O16S (1075.2 g/mol). GHK-Cu is a peptide-copper complex; SNAP-8 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 SNAP-8 in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 13.343 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 SNAP-8 in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 133.4 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 SNAP-8 in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 26.685 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 SNAP-8 in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 53.37 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 SNAP-8 in moles?
