The foetal and maternal lipids of romney sheep: II. The fatty acid composition of the lipids from the total tissues

摘要: Abstract The fatty acid composition of the triglycerides (neutral lipids) and phospholipids total tissues foetal maternal sheep has been examined. Although compositions foetus ewe were generally similar, lacking in n -C 15 , 17 saturated, - unsaturated, branched-chain C 16 acids, octadecadienoic, octadecatrienoic especially trans acids by comparison with triglycerides. was relatively high content 20 22 highly unsaturated together low 18 di- tri-unsaturated suggested that latter more actively converted to polyunsaturated than tissues. phospholipids, while containing substantial amounts did not conform respect their stearic palmitic contents general pattern differences between mammalian On other hand phosphadityl choline phosphatidyl ethanolamine fractions keeping results investigators obtained for appearance exogenous entirely phospholipid fraction, which contained less 15% similar patterns distribution suggests may penetrate placenta as diglycerides or monoglycerides derived from phospholipids. possibility direct penetration intact through is counterindicated work on species. permeable, however, excluded.
