What is the difference between GHK-Cu and Pal-GHK?
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 Pal-GHK?
GHK-Cu has a molecular weight of about 402.92 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so Pal-GHK is heavier by 175.9 g/mol, a ratio of 1.44. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK 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 Pal-GHK (MW 578.8) weighs 1.437 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Pal-GHK
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). GHK-Cu is a peptide-copper complex; Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHK-Cu equals how many mg of Pal-GHK in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 7.183 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 Pal-GHK in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 71.826 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 Pal-GHK in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 14.365 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 Pal-GHK in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 28.73 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 Pal-GHK in moles?
30 mg of GHK-Cu (MW 402.92) is 74.456 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 43.095 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 Pal-GHK in moles?
100 mg of GHK-Cu (MW 402.92) is 248.2 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 143.7 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Pal-GHK equals how many mg of GHK-Cu in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 6.961 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
