What is the difference between SS-31 and Tirzepatide?
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 Tirzepatide?
SS-31 has a molecular weight of about 639.8 g/mol and Tirzepatide about 4813 g/mol (PubChem), so Tirzepatide is heavier by 4,173.2 g/mol, a ratio of 7.52. This means 1 mg of SS-31 contains 1,563 nmol versus 207.8 nmol for Tirzepatide.
How many mg of Tirzepatide 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 Tirzepatide (MW 4813) weighs 7.523 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of SS-31 and Tirzepatide
PubChem lists SS-31 as C32H49N9O5 (639.8 g/mol) and Tirzepatide as C225H348N48O68 (4813 g/mol). SS-31 is a peptide; Tirzepatide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
