What is the difference between Semaglutide and Sermorelin?
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 Sermorelin?
Semaglutide has a molecular weight of about 4114 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Semaglutide is heavier by 756.1 g/mol, a ratio of 1.23. This means 1 mg of Semaglutide contains 243.1 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin are equimolar to 1 mg of Semaglutide?
1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of Sermorelin (MW 3357.9) weighs 0.8162 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semaglutide and Sermorelin
PubChem lists Semaglutide as C187H291N45O59 (4114 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). Semaglutide is a peptide (lipidated); Sermorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
