What is the difference between NAD+ and Selank?

Which is heavier, NAD+ or Selank?

NAD+ has a molecular weight of about 663.4 g/mol and Selank about 751.9 g/mol (PubChem), so Selank is heavier by 88.5 g/mol, a ratio of 1.13. This means 1 mg of NAD+ contains 1,507.4 nmol versus 1,330 nmol for Selank.

How many mg of Selank 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 Selank (MW 751.9) weighs 1.133 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of NAD+ and Selank

PubChem lists NAD+ as C21H27N7O14P2 (663.4 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). NAD+ is a dinucleotide coenzyme (not a peptide); Selank 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 Selank in moles?

100 mg of NAD+ (MW 663.4) is 150.7 µmol. The same amount of Selank (MW 751.9) would weigh 113.3 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 Selank in moles?

250 mg of NAD+ (MW 663.4) is 376.8 µmol. The same amount of Selank (MW 751.9) would weigh 283.4 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 Selank in moles?

500 mg of NAD+ (MW 663.4) is 753.7 µmol. The same amount of Selank (MW 751.9) would weigh 566.7 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 Selank in moles?

1000 mg of NAD+ (MW 663.4) is 1,507.4 µmol. The same amount of Selank (MW 751.9) would weigh 1,133.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of Selank equals how many mg of NAD+ in moles?

5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of NAD+ (MW 663.4) would weigh 4.411 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 NAD+ in moles?

10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of NAD+ (MW 663.4) would weigh 8.823 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
