What is the difference between Selank and Pal-GHK?
Selank is a synthetic heptapeptide analogue of tuftsin extended with Pro-Gly-Pro, developed at the Institute of Molecular Genetics in Russia and studied in neuropeptide research (peptide, MW about 751.9 g/mol).
Which is heavier, Selank or Pal-GHK?
Selank has a molecular weight of about 751.9 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so Selank is heavier by 173.1 g/mol, a ratio of 1.3. This means 1 mg of Selank contains 1,330 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.7698 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Selank and Pal-GHK
PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). Selank 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 Selank in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of Selank (MW 751.9) would weigh 12.991 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Selank equals how many mg of Pal-GHK in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 3.849 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Selank equals how many mg of Pal-GHK in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 7.698 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
