What is the difference between Semaglutide and Tesamorelin?

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 Tesamorelin?

Semaglutide has a molecular weight of about 4114 g/mol and Tesamorelin about 5136 g/mol (PubChem), so Tesamorelin is heavier by 1,022 g/mol, a ratio of 1.25. This means 1 mg of Semaglutide contains 243.1 nmol versus 194.7 nmol for Tesamorelin.

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

1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of Tesamorelin (MW 5136) weighs 1.248 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Semaglutide and Tesamorelin

PubChem lists Semaglutide as C187H291N45O59 (4114 g/mol) and Tesamorelin as C221H366N72O67S (5136 g/mol). Semaglutide is a peptide (lipidated); Tesamorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
