What is the difference between SS-31 and N-Acetyl Epitalon?
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 N-Acetyl Epitalon?
SS-31 has a molecular weight of about 639.8 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so SS-31 is heavier by 207.4 g/mol, a ratio of 1.48. This means 1 mg of SS-31 contains 1,563 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon 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 N-Acetyl Epitalon (MW 432.38) weighs 0.6758 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and N-Acetyl Epitalon
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). SS-31 is a peptide; N-Acetyl Epitalon 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 N-Acetyl Epitalon in moles?
5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 3.379 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 N-Acetyl Epitalon in moles?
10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 6.758 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
