  • Patent number: 6200624
    Abstract: This invention is directed to the use of triglycerides containing fatty ester moieties that include arachidonic acid (AA) and docosahexaenoic acid (DHA) in enteral nutritionals or nutritional supplements. These triglycerides are derived from lipid mixtures which have high levels of sterols and phosphorous. A preferred embodiment of the invention comprises an infant or enteral nutritional, or nutritional supplement, that comprises a lipid source derived from egg yolk. The lipid source derived from egg yolk is prepared by transesterification or hydrolysis, subjecting the mixture to distillation, and esterification with glycerin to result in a triglyceride containing the desired fatty acids of AA and DHA and little or no sterols and phosphorus.

  • Patent number: 6103943
    Abstract: Disclosed is a process for the synthesis of 3-buten-1-ol by contacting 3,4-epoxy-1-butene and formic acid with a homogeneous catalyst solution comprising a palladium(0) compound, a tertiary phosphine and a trialkylamine dissolved in tetrahydrofuran.

  • Patent number: 5883273
    Abstract: Fatty acid esters such as those containing arachidonic acid (AA) and docosahexaenoic acid (DHA) derived from lipid mixtures are prepared with reduced levels of sterols and phosphorus. A preferred embodiment of the invention comprises extracting lipids from egg with methanol; separating lipids including sterols from insoluble egg components; submitting the methanolic solution of lipids to transesterification and subsequent neutralization to convert the lipids to methyl esters of said free fatty acids together with sterols; separating the said sterols and esters from an aqueous phase including phosphorus compounds formed in the transesterification; subjecting the said fatty acid esters and sterols to distillation to separate sterols from the fatty acid esters; and subjecting the said esters to transesterification in the presence of glycerol to produce triglycerides of said esters thereof including that of AA and DHA wherein the resulting triglycerides contain reduced quantities of sterols and phosphorus.
