Abstract
Currently available cultivars of high erucic acid rape (HEAR) have a theoretical maximum of 66% erucic acid (22:1, Δ13) in their seed oil due to the specificity of the membrane-bound 1-acyl-sn-glycerol-3-phosphate acyltransferase (LPA-AT) enzyme. In HEAR the LPA-AT does not incorporate erucic acid at the s n-2 position of triacylglycerols (TAG) but preferentially incorporates oleic acid (18:1, Δ9), even if this is only a minor component of the total fatty acid pool (1). However, some plant species, e.g Limnanthes, can utilise erucoyl-CoA as a substrate and effectively incorporate erucic acid at the sn-2 position (2, 3).
