What is the difference between Sermorelin and Pal-GHK?
Sermorelin is the 29-residue N-terminal fragment of growth hormone-releasing hormone, the shortest fully active GHRH fragment, used in GHRH receptor research (peptide, MW about 3357.9 g/mol).
Which is heavier, Sermorelin or Pal-GHK?
Sermorelin has a molecular weight of about 3357.9 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so Sermorelin is heavier by 2,779.1 g/mol, a ratio of 5.8. This means 1 mg of Sermorelin contains 297.8 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of Sermorelin?
1 mg of Sermorelin (MW 3357.9) is 297.8 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.1724 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Sermorelin and Pal-GHK
PubChem lists Sermorelin as C149H246N44O42S (3357.9 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). Sermorelin is a peptide; Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Pal-GHK equals how many mg of Sermorelin in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 58.015 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Sermorelin equals how many mg of Pal-GHK in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.3447 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Sermorelin equals how many mg of Pal-GHK in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.8618 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Sermorelin equals how many mg of Pal-GHK in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 1.724 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
