What is the difference between Selank and Vesugen?
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 Vesugen?
Selank has a molecular weight of about 751.9 g/mol and Vesugen about 390.39 g/mol (PubChem), so Selank is heavier by 361.5 g/mol, a ratio of 1.93. This means 1 mg of Selank contains 1,330 nmol versus 2,561.5 nmol for Vesugen.
How many mg of Vesugen are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Vesugen (MW 390.39) weighs 0.5192 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Selank and Vesugen
PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Vesugen as C15H26N4O8 (390.39 g/mol). Selank is a peptide; Vesugen 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 Vesugen in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Vesugen (MW 390.39) would weigh 2.596 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 Vesugen in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Vesugen (MW 390.39) would weigh 5.192 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Vesugen equals how many mg of Selank in moles?
20 mg of Vesugen (MW 390.39) is 51.231 µmol. The same amount of Selank (MW 751.9) would weigh 38.52 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Vesugen equals how many mg of Selank in moles?
10 mg of Vesugen (MW 390.39) is 25.615 µmol. The same amount of Selank (MW 751.9) would weigh 19.26 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
