What is the difference between SS-31 and Vesugen?
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 Vesugen?
SS-31 has a molecular weight of about 639.8 g/mol and Vesugen about 390.39 g/mol (PubChem), so SS-31 is heavier by 249.4 g/mol, a ratio of 1.64. This means 1 mg of SS-31 contains 1,563 nmol versus 2,561.5 nmol for Vesugen.
How many mg of Vesugen 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 Vesugen (MW 390.39) weighs 0.6102 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and Vesugen
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and Vesugen as C15H26N4O8 (390.39 g/mol). SS-31 is a peptide; Vesugen is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of SS-31 equals how many mg of Vesugen in moles?
5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of Vesugen (MW 390.39) would weigh 3.051 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 Vesugen in moles?
10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of Vesugen (MW 390.39) would weigh 6.102 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Vesugen equals how many mg of SS-31 in moles?
20 mg of Vesugen (MW 390.39) is 51.231 µmol. The same amount of SS-31 (MW 639.8) would weigh 32.777 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Vesugen equals how many mg of SS-31 in moles?
10 mg of Vesugen (MW 390.39) is 25.615 µmol. The same amount of SS-31 (MW 639.8) would weigh 16.389 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
