标题 :Fatty acids as co-catalysts in preparation of glycerides from ethyl esters
发明人：SAEBO ASGEIR
权利人:SAEBO ASGEIR; PHARMA MARINE AS
摘要:Methods of producing concentrates of omega-3 fatty acid ethyl esters, from an ethyl ester composition comprising use of free fatty acids as co-catalysts for enzymatic synthesis of partial glycerides are provided. In some embodiments, methods of producing concentrates of ethyl-eicosapentanoate and/or ethyl-docosahexanoate from an ethyl ester composition containing the esters comprise a) adding glycerol, an immobilized enzyme catalyst, and a free fatty acid co-catalyst b) allow glyceryl ester synthesis to proceed by adjustment of temperatures, time and vacuum such that a substantial amount of partial glycerides is formed and c) separating an ethyl ester fraction enriched in ethyl eicosanoate and ethyl docosahexanoate from the glyceride mixture.

摘要:The present invention relates to compositions and methods for preparing poly-unsaturated long chain fatty acids in plants, plant parts and plant cells, such as leaves, roots, fruits and seeds. Nucleic acid sequences and constructs encoding fatty acid desaturases, including Δ5-desaturases, Δ6-desaturases and Δ12-desaturases, are used to generate transgenic plants, plant parts and cells which contain and express one or more transgenes encoding one or more desaturases. Expression of the desaturases with different substrate specificities in the plant system permit the large scale production of poly-unsaturated long chain fatty acids such as docosahexaenoic acid, eicosapentaenoic acid, α-linoleic acid, gamma-linolenic acid, arachidonic acid and the like for modification of the fatty acid profile of plants, plant parts and tissues. Manipulation of the fatty acid profiles allows for the production of commercial quantities of novel plant oils and products.

摘要:Isolated nucleic acid molecules, designated LMRP nucleic acid molecules, which encode novel LMRPs from e.g. Physcomitrella patens are described. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing LMRP nucleic acid molecules, and host cells into which the expression vectors have been introduced. The invention still further provides isolated LMRPs, mutated LMRPs, fusion proteins, antigenic peptides and methods for the improvement of production of a desired compound from transformed cells, organisms or plants based on genetic engineering of LMRP genes in these organisms.

摘要:The present invention relates to compositions and methods for preparing poly-unsaturated long chain fatty acids in plants, plant parts and plant cells, such as leaves, roots, fruits and seeds. Nucleic acid sequences and constructs encoding fatty acid desaturases, including DELTA 5-desaturases, DELTA 6-desaturases and DELTA 12-desaturases, are used to generate transgenic plants, plant parts and cells which contain and express one or more transgenes encoding one or more desaturases. Expression of the desaturases with different substrate specificities in the plant system permit the large scale production of poly-unsaturated long chain fatty acids such as docosahexaenoic acid, eicosapentaenoic acid, alpha -linoleic acid, gamma-linolenic acid, arachidonic acid and the like for modification of the fatty acid profile of plants, plant parts and tissues. Manipulation of the fatty acid profiles allows for the production of commercial quantities of novel plant oils and products.
