Altered composition of intestinal FFA, DG and TG in L-Fabp−/−ApcMin/+ mice by lipidomics. A, altered relative abundance of FFA species with shift to PUFA species in L-Fabp−/−ApcMin/+ mice. B, altered relative abundance of FA species in DG between genotypes. DG from ApcMin/+ mice have an increased proportion of 18:0 FAs and arachidonic acid (20:4). C, altered relative abundance of FA species in TG. TG from ApcMin/+ mice displayed increased relative abundance of saturated FAs and arachidonic acid (20:4). D, altered mRNA abundance of enzymes involved in FA biosynthesis, elongation and desaturation.
