What is the difference between SS-31 and Cartalax?
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 Cartalax?
SS-31 has a molecular weight of about 639.8 g/mol and Cartalax about 333.29 g/mol (PubChem), so SS-31 is heavier by 306.5 g/mol, a ratio of 1.92. This means 1 mg of SS-31 contains 1,563 nmol versus 3,000.4 nmol for Cartalax.
How many mg of Cartalax 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 Cartalax (MW 333.29) weighs 0.5209 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and Cartalax
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and Cartalax as C12H19N3O8 (333.29 g/mol). SS-31 is a peptide; Cartalax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Cartalax equals how many mg of SS-31 in moles?
10 mg of Cartalax (MW 333.29) is 30.004 µmol. The same amount of SS-31 (MW 639.8) would weigh 19.196 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Cartalax equals how many mg of SS-31 in moles?
20 mg of Cartalax (MW 333.29) is 60.008 µmol. The same amount of SS-31 (MW 639.8) would weigh 38.393 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 Cartalax in moles?
5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of Cartalax (MW 333.29) would weigh 2.605 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 Cartalax in moles?
10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of Cartalax (MW 333.29) would weigh 5.209 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
