长链多不饱和脂肪酸——花生四烯酸(AA)和二十二碳六烯酸(DHA)是生物膜的重要脂类成分。在孕期,长链多不饱和脂肪酸(LC-PUFA)首先通过胎盘从母体传递给胎儿,这种胎盘传递是由各种特异的脂肪酸结合与转运蛋白介导的。用稳定同位素方法进行的研究表明,出生后,早产儿和足月婴儿可以将亚油酸和 a-亚油酸分别转化成AA 和 DHA。但是,这种内源性合成 LC-PUFA 的活力
Long-chain polyunsaturated fatty acids - arachidonic acid (AA) and docosahexaenoic acid (DHA) are important lipid components of biomembranes. During pregnancy, long-chain polyunsaturated fatty acids (LC-PUFA) are first transmitted from the mother to the fetus through the placenta, which is mediated by a variety of specific fatty acid binding and transporter proteins. Studies using stable isotope methods show that preterm and term infants can convert linoleic acid and a-linoleic acid to AA and DHA, respectively, after birth. However, this endogenous synthesis of LC-PUFA activity
