What is the difference between Semaglutide and Semax?

Semaglutide is a GLP-1 receptor agonist peptide with an Aib substitution at position 8 and a C18 fatty diacid on Lys26 for albumin binding, studied in incretin receptor pharmacology (peptide (lipidated), MW about 4114 g/mol).

Which is heavier, Semaglutide or Semax?

Semaglutide has a molecular weight of about 4114 g/mol and Semax about 813.9 g/mol (PubChem), so Semaglutide is heavier by 3,300.1 g/mol, a ratio of 5.05. This means 1 mg of Semaglutide contains 243.1 nmol versus 1,228.7 nmol for Semax.

How many mg of Semax are equimolar to 1 mg of Semaglutide?

1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of Semax (MW 813.9) weighs 0.1978 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Semaglutide and Semax

PubChem lists Semaglutide as C187H291N45O59 (4114 g/mol) and Semax as C37H51N9O10S (813.9 g/mol). Semaglutide is a peptide (lipidated); Semax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
