| Abstract: | Lipids in developing as well as mature seeds of Lunaria annua are mainly composed of triacylglycerols which contain almost exclusively nervonoyl (24:1), erucoyl (22:1) and oleoyl (18:1) moieties. Maturation of the seeds proceeds with successive reduction in the relative proportions of phospholipids and glycolipids as well as linoleoyl (18:2) and linolenoyl (18:3) moieties in the total lipids. Concomitantly, the most predominant fraction of triacylglycerols, which contain nervonoyl and erucoyl moieties at the sn-1,3 positions and oleoyl moieties at the sn-2 position, are accumulated. |
