What is the difference between SS-31 and Vilon?
SS-31 is a mitochondria-targeted tetrapeptide (Szeto-Schiller peptide) that associates with cardiolipin in the inner mitochondrial membrane, studied in mitochondrial bioenergetics research (peptide, MW about 639.8 g/mol).
Which is heavier, SS-31 or Vilon?
SS-31 has a molecular weight of about 639.8 g/mol and Vilon about 275.3 g/mol (PubChem), so SS-31 is heavier by 364.5 g/mol, a ratio of 2.32. This means 1 mg of SS-31 contains 1,563 nmol versus 3,632.4 nmol for Vilon.
How many mg of Vilon are equimolar to 1 mg of SS-31?
1 mg of SS-31 (MW 639.8) is 1,563 nmol. The same number of moles of Vilon (MW 275.3) weighs 0.4303 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and Vilon
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and Vilon as C11H21N3O5 (275.3 g/mol). SS-31 is a peptide; Vilon is a dipeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of SS-31 equals how many mg of Vilon in moles?
5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of Vilon (MW 275.3) would weigh 2.151 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 Vilon in moles?
10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of Vilon (MW 275.3) would weigh 4.303 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Vilon equals how many mg of SS-31 in moles?
10 mg of Vilon (MW 275.3) is 36.324 µmol. The same amount of SS-31 (MW 639.8) would weigh 23.24 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Vilon equals how many mg of SS-31 in moles?
20 mg of Vilon (MW 275.3) is 72.648 µmol. The same amount of SS-31 (MW 639.8) would weigh 46.48 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
