What is the difference between Semax and Vesugen?
Semax is a heptapeptide analogue of the ACTH(4-7) fragment extended with Pro-Gly-Pro, studied in neuropeptide and BDNF-expression research in rodent models (peptide, MW about 813.9 g/mol).
Which is heavier, Semax or Vesugen?
Semax has a molecular weight of about 813.9 g/mol and Vesugen about 390.39 g/mol (PubChem), so Semax is heavier by 423.5 g/mol, a ratio of 2.08. This means 1 mg of Semax contains 1,228.7 nmol versus 2,561.5 nmol for Vesugen.
How many mg of Vesugen are equimolar to 1 mg of Semax?
1 mg of Semax (MW 813.9) is 1,228.7 nmol. The same number of moles of Vesugen (MW 390.39) weighs 0.4797 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semax and Vesugen
PubChem lists Semax as C37H51N9O10S (813.9 g/mol) and Vesugen as C15H26N4O8 (390.39 g/mol). Semax is a peptide; Vesugen is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Semax equals how many mg of Vesugen in moles?
5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of Vesugen (MW 390.39) would weigh 2.398 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Semax equals how many mg of Vesugen in moles?
10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of Vesugen (MW 390.39) would weigh 4.797 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of Semax equals how many mg of Vesugen in moles?
30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of Vesugen (MW 390.39) would weigh 14.39 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 Semax in moles?
20 mg of Vesugen (MW 390.39) is 51.231 µmol. The same amount of Semax (MW 813.9) would weigh 41.697 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 Semax in moles?
10 mg of Vesugen (MW 390.39) is 25.615 µmol. The same amount of Semax (MW 813.9) would weigh 20.848 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
