Fatty acid composition of phospholipid (PL) classes was measured in mouse testis. Among the long-chain polyenoic acids (LCPA), 22:6 was found in highest concentration in phosphatidylethanolamine (PE), whereas percentages of 20:4 and 22:5 were not different in PE than in phosphatidycholine. Each PL class had a unique fatty acid composition which was also different from that of triglycerides and cholesteryl esters. Differential metabolisms of 22:5 and 22:6 suggest different roles for these fatty acids in mouse testis. Tissue-specific functions of LCPA in mouse spermatogenesis may be divided between 22:5 and 22:6.
对小鼠睾丸中磷脂（PL）类别的脂肪酸组成进行了测定。在长链多烯酸（LCPA）中，22:6在磷脂酰乙醇胺（PE）中的浓度最高，而20:4和22:5在PE中的百分比与在磷脂酰胆碱中的百分比没有差异。每种PL类别都有独特的脂肪酸组成，这也与甘油三酯和胆固醇酯的脂肪酸组成不同。22:5和22:6的不同代谢表明这些脂肪酸在小鼠睾丸中具有不同的作用。LCPA在小鼠精子发生中的组织特异性功能可能在22:5和22:6之间有所区分。
