Figure. Concentration-dependent activation of GPR119 by N-oleoyl­ethanol­amine. Reporter cells were transfected with either the expression plasmid for G protein-coupled receptor 119 (GPR119) or the mock plasmid and treated with various concentrations of N-oleoyl­ethanol­amine. Data points shown are the mean ± SEM of an experiment performed in triplicate, and the curve is a fit to Hill equation with an EC50 of 6.3 µM.
