Figure 4: Comprehensive analysis of ischemia/reperfusion-induced levels of NAPE molecular species with acyl chains N-16:0, N-18:0 and N-18:1, in contralateral (IC) and ipsilateral (II) brain tissue of groups treated with vehicle or exogenous NAE 16:0. Data are shown as mean ± SD and N = 4. NAPE molecular species labels indicate the diacyl component (total acyl carbons: total carbon-carbon double bonds) of each detected NAPE species. NAPE species mass spectral signals were normalized against the signal, assigned to be 1 unit, observed for 1 nmol of the internal standard, N-17:0 di16:0 PE.
