What is the difference between SS-31 and Semaglutide?
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 Semaglutide?
SS-31 has a molecular weight of about 639.8 g/mol and Semaglutide about 4114 g/mol (PubChem), so Semaglutide is heavier by 3,474.2 g/mol, a ratio of 6.43. This means 1 mg of SS-31 contains 1,563 nmol versus 243.1 nmol for Semaglutide.
How many mg of Semaglutide 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 Semaglutide (MW 4114) weighs 6.43 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and Semaglutide
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and Semaglutide as C187H291N45O59 (4114 g/mol). SS-31 is a peptide; Semaglutide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
