Estimating the term…
The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain poly unsaturated fatty acids.
A process for producing oil containing eicosapentaenoic acid, docosahexaenoic acid and docosapentaenoic acid, comprising the steps of obtaining a tranagenic oil-seed rape seed, a tranagenic cotton seed or a tranagenic flax seed comprising eicosapentaenoic acid, docosahexaenoic acid and docosapentaenoic acid, wherein at least 25% (w/w) of the eiscosapentaenoic acid, docosahexaenoic acid and docosapentaenoic acid of the transgenic seed is incorporated into triacylglycerols in the transgenic seed, and wherein the total fatty acid in the oil of the transgenic seed comprises at least 2.5% ω3 C20 fatty acids (w/w), and extracting oil from the transgenic seed so as to thereby produce the oil.
