Metabolic studies of glyceride esters of adipic acid

Data on the digestibility, absorption, and in vivo oxidation of two types of adipic acid esters of glycerides, a diglyceride adipate and a polymer of fatty acids, adipic acid, and glycerol, have been presented. Findings indicate that these compounds have high digestibility coefficients and that the stearic acid moiety is well absorbed. However, although the stearic acid moieties are oxidized slowly in both cases, which is compatible with previous findings that a slow rate of in vivo oxidation of the stearic acid moiety of glycerides obtains (6), the rate of oxidation of the stearic acid is greater when fed as the diglyceride adipate than as the polyester.
