the mechanism of intestinal absorption of polyunsaturated phosphatidylcholine in an oil medium was studied with 1,2-di- [ 9,10,12,13-3h4 ] linoleoyl-sn-glycero-3-phospho- [ n-14ch3 ] -choline , 1- [ 1-14c ] linoleoyl-2- [ 9,10,12,13-3h4 ] -linoleoyl- and 1- [ 9,10,12,13-3h4 ] linoleoyl-2- [ 1-14c ] linoleoyl-sn-glycero-3-phosphocholine , especially with regard to the stability of the ester bonds in position 1 and 2 of the phospholipid molecule .
