What is the difference between KPV and SS-31?
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone, studied in inflammation-signalling research in cell and rodent models (peptide, MW about 342.43 g/mol).
Which is heavier, KPV or SS-31?
KPV has a molecular weight of about 342.43 g/mol and SS-31 about 639.8 g/mol (PubChem), so SS-31 is heavier by 297.4 g/mol, a ratio of 1.87. This means 1 mg of KPV contains 2,920.3 nmol versus 1,563 nmol for SS-31.
How many mg of SS-31 are equimolar to 1 mg of KPV?
1 mg of KPV (MW 342.43) is 2,920.3 nmol. The same number of moles of SS-31 (MW 639.8) weighs 1.868 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of KPV and SS-31
PubChem lists KPV as C16H30N4O4 (342.43 g/mol) and SS-31 as C32H49N9O5 (639.8 g/mol). KPV is a peptide; SS-31 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of KPV equals how many mg of SS-31 in moles?
2 mg of KPV (MW 342.43) is 5.841 µmol. The same amount of SS-31 (MW 639.8) would weigh 3.737 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of KPV equals how many mg of SS-31 in moles?
5 mg of KPV (MW 342.43) is 14.602 µmol. The same amount of SS-31 (MW 639.8) would weigh 9.342 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of KPV equals how many mg of SS-31 in moles?
10 mg of KPV (MW 342.43) is 29.203 µmol. The same amount of SS-31 (MW 639.8) would weigh 18.684 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of KPV equals how many mg of SS-31 in moles?
20 mg of KPV (MW 342.43) is 58.406 µmol. The same amount of SS-31 (MW 639.8) would weigh 37.368 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of SS-31 equals how many mg of KPV in moles?
5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of KPV (MW 342.43) would weigh 2.676 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of SS-31 equals how many mg of KPV in moles?
10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of KPV (MW 342.43) would weigh 5.352 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
