Insulin Detemir Side Chain

Marketed as the brand name product Levemir, insulin detemir has a duration of action of 16-24 hours allowing for once-daily dosing. Levemir is considered "basal insulin" as it provides low concentrations of background insulin that can keep blood sugar stable between meals or overnight.

Insulin detemir is produced using recombinant DNA technology in yeast cells. This insulin analogue has a 14-C fatty acid, myristic acid, bound to the lysine amino acid at position B29. The myristoyl side chain increases self-association and albumin binding. This along with slow systemic absorption from the injection site prolongs distribution of the hormone into tissues and results in a long duration of action.

SINOPEG is pleased to offer this C-14 fatty acid for your R&D and clinic research.
