What is the difference between Semax and Tirzepatide?
Semax is a heptapeptide analogue of the ACTH(4-7) fragment extended with Pro-Gly-Pro, studied in neuropeptide and BDNF-expression research in rodent models (peptide, MW about 813.9 g/mol).
Which is heavier, Semax or Tirzepatide?
Semax has a molecular weight of about 813.9 g/mol and Tirzepatide about 4813 g/mol (PubChem), so Tirzepatide is heavier by 3,999.1 g/mol, a ratio of 5.91. This means 1 mg of Semax contains 1,228.7 nmol versus 207.8 nmol for Tirzepatide.
How many mg of Tirzepatide are equimolar to 1 mg of Semax?
1 mg of Semax (MW 813.9) is 1,228.7 nmol. The same number of moles of Tirzepatide (MW 4813) weighs 5.914 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semax and Tirzepatide
PubChem lists Semax as C37H51N9O10S (813.9 g/mol) and Tirzepatide as C225H348N48O68 (4813 g/mol). Semax is a peptide; Tirzepatide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
