What is the difference between GHK-Cu and Thymosin alpha-1?
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 Thymosin alpha-1?
GHK-Cu has a molecular weight of about 402.92 g/mol and Thymosin alpha-1 about 3108.3 g/mol (PubChem), so Thymosin alpha-1 is heavier by 2,705.4 g/mol, a ratio of 7.71. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 321.7 nmol for Thymosin alpha-1.
How many mg of Thymosin alpha-1 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 Thymosin alpha-1 (MW 3108.3) weighs 7.714 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Thymosin alpha-1
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Thymosin alpha-1 as C129H215N33O55 (3108.3 g/mol). GHK-Cu is a peptide-copper complex; Thymosin alpha-1 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 Thymosin alpha-1 in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 38.572 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 Thymosin alpha-1 in moles?
