What is the difference between GHRP-6 and Pal-GHK?
GHRP-6 is one of the earliest synthetic growth hormone secretagogue hexapeptides, used as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 873 g/mol).
Which is heavier, GHRP-6 or Pal-GHK?
GHRP-6 has a molecular weight of about 873 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so GHRP-6 is heavier by 294.2 g/mol, a ratio of 1.51. This means 1 mg of GHRP-6 contains 1,145.5 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of GHRP-6?
1 mg of GHRP-6 (MW 873) is 1,145.5 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.663 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-6 and Pal-GHK
PubChem lists GHRP-6 as C46H56N12O6 (873 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). GHRP-6 is a peptide; Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-6 equals how many mg of Pal-GHK in moles?
5 mg of GHRP-6 (MW 873) is 5.727 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 3.315 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-6 equals how many mg of Pal-GHK in moles?
10 mg of GHRP-6 (MW 873) is 11.455 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 6.63 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Pal-GHK equals how many mg of GHRP-6 in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of GHRP-6 (MW 873) would weigh 15.083 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
