What is the difference between SS-31 and SNAP-8?
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 SNAP-8?
SS-31 has a molecular weight of about 639.8 g/mol and SNAP-8 about 1075.2 g/mol (PubChem), so SNAP-8 is heavier by 435.4 g/mol, a ratio of 1.68. This means 1 mg of SS-31 contains 1,563 nmol versus 930.1 nmol for SNAP-8.
How many mg of SNAP-8 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 SNAP-8 (MW 1075.2) weighs 1.681 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and SNAP-8
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and SNAP-8 as C41H70N16O16S (1075.2 g/mol). SS-31 is a peptide; SNAP-8 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of SNAP-8 equals how many mg of SS-31 in moles?
5 mg of SNAP-8 (MW 1075.2) is 4.65 µmol. The same amount of SS-31 (MW 639.8) would weigh 2.975 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of SNAP-8 equals how many mg of SS-31 in moles?
10 mg of SNAP-8 (MW 1075.2) is 9.301 µmol. The same amount of SS-31 (MW 639.8) would weigh 5.951 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 SNAP-8 in moles?
5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 8.403 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 SNAP-8 in moles?
10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 16.805 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
