What is the difference between Ipamorelin and Pal-GHK?
Ipamorelin is a pentapeptide ghrelin receptor agonist reported in 1998 as a selective growth hormone secretagogue in endocrine research (peptide, MW about 711.9 g/mol).
Which is heavier, Ipamorelin or Pal-GHK?
Ipamorelin has a molecular weight of about 711.9 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so Ipamorelin is heavier by 133.1 g/mol, a ratio of 1.23. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of Ipamorelin?
1 mg of Ipamorelin (MW 711.9) is 1,404.7 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.813 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Ipamorelin and Pal-GHK
PubChem lists Ipamorelin as C38H49N9O5 (711.9 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). Ipamorelin is a peptide; Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Ipamorelin equals how many mg of Pal-GHK in moles?
2 mg of Ipamorelin (MW 711.9) is 2.809 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 1.626 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Ipamorelin equals how many mg of Pal-GHK in moles?
10 mg of Ipamorelin (MW 711.9) is 14.047 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 8.13 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Ipamorelin equals how many mg of Pal-GHK in moles?
5 mg of Ipamorelin (MW 711.9) is 7.023 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 4.065 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 Ipamorelin in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 12.3 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
