What is the difference between Semax and Pinealon?
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 Pinealon?
Semax has a molecular weight of about 813.9 g/mol and Pinealon about 418.4 g/mol (PubChem), so Semax is heavier by 395.5 g/mol, a ratio of 1.95. This means 1 mg of Semax contains 1,228.7 nmol versus 2,390.1 nmol for Pinealon.
How many mg of Pinealon 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 Pinealon (MW 418.4) weighs 0.5141 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semax and Pinealon
PubChem lists Semax as C37H51N9O10S (813.9 g/mol) and Pinealon as C15H26N6O8 (418.4 g/mol). Semax is a peptide; Pinealon is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Pinealon equals how many mg of Semax in moles?
10 mg of Pinealon (MW 418.4) is 23.901 µmol. The same amount of Semax (MW 813.9) would weigh 19.453 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Pinealon equals how many mg of Semax in moles?
20 mg of Pinealon (MW 418.4) is 47.801 µmol. The same amount of Semax (MW 813.9) would weigh 38.905 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Semax equals how many mg of Pinealon in moles?
5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of Pinealon (MW 418.4) would weigh 2.57 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 Pinealon in moles?
10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of Pinealon (MW 418.4) would weigh 5.141 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 Pinealon in moles?
30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of Pinealon (MW 418.4) would weigh 15.422 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
