What is the difference between Semaglutide and Matrixyl?
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 Matrixyl?
Semaglutide has a molecular weight of about 4114 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Semaglutide is heavier by 3,311.9 g/mol, a ratio of 5.13. This means 1 mg of Semaglutide contains 243.1 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl are equimolar to 1 mg of Semaglutide?
1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of Matrixyl (MW 802.1) weighs 0.195 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semaglutide and Matrixyl
PubChem lists Semaglutide as C187H291N45O59 (4114 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Semaglutide is a peptide (lipidated); Matrixyl is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Matrixyl equals how many mg of Semaglutide in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Semaglutide (MW 4114) would weigh 25.645 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
