What is the difference between Semaglutide and IGF-1 LR3?
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 IGF-1 LR3?
Semaglutide has a molecular weight of about 4114 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 4,997 g/mol, a ratio of 2.21. This means 1 mg of Semaglutide contains 243.1 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Semaglutide?
1 mg of Semaglutide (MW 4114) is 243.1 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 2.215 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 0.1 mg vial of IGF-1 LR3 equals how many mg of Semaglutide in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Semaglutide (MW 4114) would weigh 0.04515 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
