Lymphatic Absorption of Structured Triacylglycerols, 1(3)-Stearoyl-2, 3(1)-Dilinoleoylglycerol and 2-Linoleoyl-1, 3-Distearoylglycerol in Rats

Lymphatic recovery of 1(3)-stearoyl-2, 3(1)-dilinoleoylglycerol (SLL) and 2-linoleoyl-1, 3-distearoylglycerol (SLS) which had been enzymatically synthesized were compared with those of trilinoleoylglycerol (LLL) and the randomly esterified triacylglycerol which contained stearic acid and linoleic acid at 1 : 2. Recoveries of linoleic acid in all of the triacylglycerols were more than 94.0%. Lymphatic 24 h-recoveries of stearic acid given as SLL and SLS were significantly lower than that of stearic acid given as the randomly esterified triacylglycerol. Recoveries of stearic acid from SLL, SLS and the randomly esterified triacylglycerol were 88.4%, 68.3% and 101%, respectively.
