Figure 5: Comprehensive analysis of ischemia/reperfusion-induced levels of NAPE molecular species with acyl chains N-18:2, N-20:4, and N-22:6, 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. �ND� indicates molecular species that were not determined (see Experimental Procedures). 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.
