Abstract
The deposition oftrans-12-octadecenoate-12(13)-3H (12t-18∶1-3H) was compared tocis-9-octadecenoate-10-14C (9c-18∶1-14C) in the major egg yolk neutral lipids and phospholipids.trans-12-Octadecenoate was preferentially incorporated into cholesteryl esters (CE), phosphatidylcholines (PC), and phosphatidylethanolamines (PE) but was discriminated against in triglycerides (TG). Isotopic ratios indicate that 5.9 and 5.6 times more 12t-18∶1-3H than 9c-18∶1-14C was esterified at the 1-acyl position of PE and PC, respectively. The combined 1- and 3-acyl positions of TG and the 2-acyl position of TG, PE and PC were each preferentially esterified with 9c-18∶1-14C.This publication has 33 references indexed in Scilit:
