  • Patent number: 8455666
    Abstract: Esters of lipoic acid with a glyceride are produced in high yield by lipase catalyzed transesterification. The esters are generally characterized by Formula 1: wherein at least one but no more than two of R1, R2, and R3 are a lipoic acid derivative selected from a lipoate moiety of the formula: or a dihydrolipoate moiety of the formula and the other of the R1, R2, and R3 are independently selected from C4 to C24 fatty acid moieties or OH, with the proviso that at least one of the R1, R2, and R3 is a fatty acid moiety.

  • Patent number: 7572610
    Abstract: A method of making a compound having the structural formula: wherein at least two of R1, R2, and R3 are non-fatty acid carboxylates, and the other of R1, R2, and R3 are each either a C2-C24 fatty acid moiety, OH, or a non-fatty acid carboxylate, wherein the first and second non-fatty acid carboxylates, when present, are the same or different, comprising (a) partially deacylating a triacylglycerol so as to provide a mono- or diacylglycerol, (b) reacting in a reaction mixture an acyl ester of the phytochemical with said mono- or diacylglycerol in the presence of a esterase catalyst under conditions that permit transesterification of said ester with said mono- or diacylglycerol, and (c) recovering said compound from said reaction mixture.
