WebAcyl editing is a deacylation-reacylation cycle of PC that exchanges the fatty acids on PC with fatty acids in the acyl-CoA pool ( Fig. 1, A and B ). Through acyl editing, newly synthesized 18:1 can be incorporated into PC for desaturation and PUFA can be released from PC to the acyl-CoA pool to be utilized for glycerolipid synthesis. how long can flu lastWebSince further desaturation of 18:1 to form 18:2 and 18:3 occurs mainly in phosphatidylcholine (PC), these alternative paths can provide PC-derived DAG species which are enriched in PUFA for TAG synthesis. Further more, an acyl editing (acyl exchange) mechanism also exists that can further enrich PUFA in oilseed TAG [ Bates09 ]. how long can flipgrid videos be
