a) Chemical structures of monooleylglycerol (C18:1 MAGE) and monooleoylglycerol (C18:1 MAG). b) Heavy-labeled C18:1 MAGE was synthesized from all-[13C]-oleic acid and was then co-extracted with 3T3-L1 cells. c) Targeted monitoring of C18:1 MAGE and C18:1 MAG levels over the course of adipocyte differentiation by isotope dilution mass spectrometry (error bars for all graphs: ± s.d.; n = 3).
