What is the difference between GHK-Cu and MOTS-c?
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 MOTS-c?
GHK-Cu has a molecular weight of about 402.92 g/mol and MOTS-c about 2174.6 g/mol (PubChem), so MOTS-c is heavier by 1,771.7 g/mol, a ratio of 5.4. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 459.9 nmol for MOTS-c.
How many mg of MOTS-c 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 MOTS-c (MW 2174.6) weighs 5.397 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and MOTS-c
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and MOTS-c as C101H152N28O22S2 (2174.6 g/mol). GHK-Cu is a peptide-copper complex; MOTS-c is a peptide. These formulas refer to the parent compounds without salt counter-ions.
