What is the difference between NAD+ and TB-500?
NAD+ is a dinucleotide coenzyme central to redox reactions and a substrate for sirtuins and PARP enzymes, used widely in biochemistry and cell-metabolism research (dinucleotide coenzyme (not a peptide), MW about 663.4 g/mol).
Which is heavier, NAD+ or TB-500?
NAD+ has a molecular weight of about 663.4 g/mol and TB-500 about 889 g/mol (PubChem), so TB-500 is heavier by 225.6 g/mol, a ratio of 1.34. This means 1 mg of NAD+ contains 1,507.4 nmol versus 1,124.9 nmol for TB-500.
How many mg of TB-500 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 TB-500 (MW 889) weighs 1.34 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of NAD+ and TB-500
PubChem lists NAD+ as C21H27N7O14P2 (663.4 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). NAD+ is a dinucleotide coenzyme (not a peptide); TB-500 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 TB-500 in moles?
100 mg of NAD+ (MW 663.4) is 150.7 µmol. The same amount of TB-500 (MW 889) would weigh 134 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 TB-500 in moles?
250 mg of NAD+ (MW 663.4) is 376.8 µmol. The same amount of TB-500 (MW 889) would weigh 335 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 TB-500 in moles?
500 mg of NAD+ (MW 663.4) is 753.7 µmol. The same amount of TB-500 (MW 889) would weigh 670 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 TB-500 in moles?
