What is the difference between Tirzepatide and IGF-1 LR3?

Tirzepatide is a 39-residue dual GIP and GLP-1 receptor agonist with a C20 fatty diacid moiety, studied in incretin receptor pharmacology (peptide (lipidated), MW about 4813 g/mol).

Which is heavier, Tirzepatide or IGF-1 LR3?

Tirzepatide has a molecular weight of about 4813 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 4,298 g/mol, a ratio of 1.89. This means 1 mg of Tirzepatide contains 207.8 nmol versus 109.8 nmol for IGF-1 LR3.

How many mg of IGF-1 LR3 are equimolar to 1 mg of Tirzepatide?

1 mg of Tirzepatide (MW 4813) is 207.8 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 1.893 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 Tirzepatide in moles?

0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Tirzepatide (MW 4813) would weigh 0.05283 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
