What is the difference between Selank and Sermorelin?
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 Sermorelin?
Selank has a molecular weight of about 751.9 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Sermorelin is heavier by 2,606 g/mol, a ratio of 4.47. This means 1 mg of Selank contains 1,330 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Sermorelin (MW 3357.9) weighs 4.466 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Selank and Sermorelin
PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). Selank is a peptide; Sermorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Selank equals how many mg of Sermorelin in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 22.329 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 Sermorelin in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 44.659 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 Selank in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of Selank (MW 751.9) would weigh 0.4478 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 Selank in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of Selank (MW 751.9) would weigh 1.12 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 Selank in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of Selank (MW 751.9) would weigh 2.239 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
