What is the difference between GHK-Cu and Matrixyl?
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 Matrixyl?
GHK-Cu has a molecular weight of about 402.92 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Matrixyl is heavier by 399.2 g/mol, a ratio of 1.99. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl 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 Matrixyl (MW 802.1) weighs 1.991 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Matrixyl
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). GHK-Cu is a peptide-copper complex; Matrixyl 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 Matrixyl in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of Matrixyl (MW 802.1) would weigh 9.954 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 Matrixyl in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of Matrixyl (MW 802.1) would weigh 99.536 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 Matrixyl in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of Matrixyl (MW 802.1) would weigh 19.907 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 Matrixyl in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of Matrixyl (MW 802.1) would weigh 39.814 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 Matrixyl in moles?
30 mg of GHK-Cu (MW 402.92) is 74.456 µmol. The same amount of Matrixyl (MW 802.1) would weigh 59.722 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 Matrixyl in moles?
100 mg of GHK-Cu (MW 402.92) is 248.2 µmol. The same amount of Matrixyl (MW 802.1) would weigh 199.1 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Matrixyl equals how many mg of GHK-Cu in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 2.512 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Matrixyl equals how many mg of GHK-Cu in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 5.023 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
