What is the difference between Semax and N-Acetyl Epitalon?
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 N-Acetyl Epitalon?
Semax has a molecular weight of about 813.9 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so Semax is heavier by 381.5 g/mol, a ratio of 1.88. This means 1 mg of Semax contains 1,228.7 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon 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 N-Acetyl Epitalon (MW 432.38) weighs 0.5312 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semax and N-Acetyl Epitalon
PubChem lists Semax as C37H51N9O10S (813.9 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). Semax is a peptide; N-Acetyl Epitalon 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 N-Acetyl Epitalon in moles?
5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 2.656 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 N-Acetyl Epitalon in moles?
10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 5.312 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 N-Acetyl Epitalon in moles?
30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 15.937 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
