What is the difference between Selank and Semaglutide?
Selank is a synthetic heptapeptide analogue of tuftsin extended with Pro-Gly-Pro, developed at the Institute of Molecular Genetics in Russia and studied in neuropeptide research (peptide, MW about 751.9 g/mol).
Which is heavier, Selank or Semaglutide?
Selank has a molecular weight of about 751.9 g/mol and Semaglutide about 4114 g/mol (PubChem), so Semaglutide is heavier by 3,362.1 g/mol, a ratio of 5.47. This means 1 mg of Selank contains 1,330 nmol versus 243.1 nmol for Semaglutide.
How many mg of Semaglutide are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Semaglutide (MW 4114) weighs 5.471 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Selank and Semaglutide
PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Semaglutide as C187H291N45O59 (4114 g/mol). Selank is a peptide; Semaglutide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
