What is the difference between GHK-Cu and Cartalax?
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 Cartalax?
GHK-Cu has a molecular weight of about 402.92 g/mol and Cartalax about 333.29 g/mol (PubChem), so GHK-Cu is heavier by 69.63 g/mol, a ratio of 1.21. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 3,000.4 nmol for Cartalax.
How many mg of Cartalax 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 Cartalax (MW 333.29) weighs 0.8272 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Cartalax
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Cartalax as C12H19N3O8 (333.29 g/mol). GHK-Cu is a peptide-copper complex; Cartalax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Cartalax equals how many mg of GHK-Cu in moles?
10 mg of Cartalax (MW 333.29) is 30.004 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 12.089 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Cartalax equals how many mg of GHK-Cu in moles?
20 mg of Cartalax (MW 333.29) is 60.008 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 24.178 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of GHK-Cu equals how many mg of Cartalax in moles?
