Feeding oils containing various proportions of the monounsaturated oleic (18:1 n-9) and petroselinic (18:1 n-12) acids to rats was found to strongly affect the levels of arachidonate (AA, 20:4 n-6) [J Nutr 1995;125: 1563–1568; Nutr Res 1997; 17: 89

Lipase from rape (Brassica napus L., immobilized onto celite, catalyzes esterification and transesterification reactions in hexane. The activity of the lipase is stimulated up to 35 fold by the addition of water (1.3% w/v). The activity of the lipase

Immobilized lipase preparations from seedlings of rape (Brassica napus L.) andMucor miehei (lipozyme) used as biocatalysts in esterification and hydrolysis reactions discriminate strongly against γ-linolenic and docosahexaenoic acids/acyl moieties.

Lipase (EC 3.1.1.3) from oilseed rape (Brassica napus L., cv Ceres) hydrolyzes triacylglycerols containing a broad range of fatty acids at similar rates. In esterification reactions carried out in hexane, rape lipase also uses a wide range of fatty a

Several commercially available lipases have been evaluated with regard to their substrate specificity in the esterification of fatty acids having specific positions of cis double bonds, e.g. petroselinic acid (n-12 18:1), alpha-linolenic acid (n-3 18

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 reduc
