What is the difference between Semaglutide and TB-500?
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 TB-500?
Semaglutide has a molecular weight of about 4114 g/mol and TB-500 about 889 g/mol (PubChem), so Semaglutide is heavier by 3,225 g/mol, a ratio of 4.63. This means 1 mg of Semaglutide contains 243.1 nmol versus 1,124.9 nmol for TB-500.
How many mg of TB-500 are equimolar to 1 mg of Semaglutide?
1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of TB-500 (MW 889) weighs 0.2161 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Semaglutide and TB-500
PubChem lists Semaglutide as C187H291N45O59 (4114 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). Semaglutide is a peptide (lipidated); TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
