What is the difference between NAD+ and Semax?

Which is heavier, NAD+ or Semax?

NAD+ has a molecular weight of about 663.4 g/mol and Semax about 813.9 g/mol (PubChem), so Semax is heavier by 150.5 g/mol, a ratio of 1.23. This means 1 mg of NAD+ contains 1,507.4 nmol versus 1,228.7 nmol for Semax.

How many mg of Semax are equimolar to 1 mg of NAD+?

1 mg of NAD+ (MW 663.4) is 1,507.4 nmol. The same number of moles of Semax (MW 813.9) weighs 1.227 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of NAD+ and Semax

PubChem lists NAD+ as C21H27N7O14P2 (663.4 g/mol) and Semax as C37H51N9O10S (813.9 g/mol). NAD+ is a dinucleotide coenzyme (not a peptide); Semax is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 100 mg vial of NAD+ equals how many mg of Semax in moles?

100 mg of NAD+ (MW 663.4) is 150.7 µmol. The same amount of Semax (MW 813.9) would weigh 122.7 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 250 mg vial of NAD+ equals how many mg of Semax in moles?

250 mg of NAD+ (MW 663.4) is 376.8 µmol. The same amount of Semax (MW 813.9) would weigh 306.7 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 500 mg vial of NAD+ equals how many mg of Semax in moles?

500 mg of NAD+ (MW 663.4) is 753.7 µmol. The same amount of Semax (MW 813.9) would weigh 613.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 1000 mg vial of NAD+ equals how many mg of Semax in moles?

1000 mg of NAD+ (MW 663.4) is 1,507.4 µmol. The same amount of Semax (MW 813.9) would weigh 1,226.9 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 NAD+ in moles?

5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of NAD+ (MW 663.4) would weigh 4.075 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 NAD+ in moles?

10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of NAD+ (MW 663.4) would weigh 8.151 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 NAD+ in moles?

30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of NAD+ (MW 663.4) would weigh 24.453 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
