What is the difference between GHK-Cu and N-Acetyl Epitalon?
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 N-Acetyl Epitalon?
GHK-Cu has a molecular weight of about 402.92 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so N-Acetyl Epitalon is heavier by 29.46 g/mol, a ratio of 1.07. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon 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 N-Acetyl Epitalon (MW 432.38) weighs 1.073 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and N-Acetyl Epitalon
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). GHK-Cu is a peptide-copper complex; N-Acetyl Epitalon 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 N-Acetyl Epitalon in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 5.366 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 N-Acetyl Epitalon in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 53.656 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 N-Acetyl Epitalon in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 10.731 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 N-Acetyl Epitalon in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 21.462 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 N-Acetyl Epitalon in moles?
30 mg of GHK-Cu (MW 402.92) is 74.456 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 32.193 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 N-Acetyl Epitalon in moles?
100 mg of GHK-Cu (MW 402.92) is 248.2 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 107.3 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
