Esters of lipoic acid with a glyceride are produced in high yield by lipase catalyzed transesterification. The esters are generally characterized by Formula 1: n nwherein at least one but no more than two of R 1 , R 2 , and R 3 are a lipoic acid derivative selected from a lipoate moiety of the formula:n n nor a dihydrolipoate moiety of the formulan n nand the other of the R 1 , R 2 , and R 3 are independently selected from C 4 to C 24 fatty acid moieties or OH, with the proviso that at least one of the R 1 , R 2 , and R 3 is a fatty acid moiety. |
