What is the difference between Semaglutide and Pal-GHK?
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 Pal-GHK?
Semaglutide has a molecular weight of about 4114 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so Semaglutide is heavier by 3,535.2 g/mol, a ratio of 7.11. This means 1 mg of Semaglutide contains 243.1 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of Semaglutide?
1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.1407 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semaglutide and Pal-GHK
PubChem lists Semaglutide as C187H291N45O59 (4114 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). Semaglutide is a peptide (lipidated); Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
