Abstract

The major individual phosphoglycerides of ram spermatozoa have specific fatty acid compositions, whereas human spermatozoan phosphoglycerides contain a similar pattern of fatty acids. The difference in the polyunsaturated:saturated fatty acid ratio of the spermatozoan phosphoglycerides between the two species were associated with the very high polyunsaturated fatty acid content of ram spermatozoan plasmalogens. The major unsaturated fatty acid of ram spermatozoa phospholipids, docosahexaenoic acid, was concentrated in the choline phosphoglycerides, whereas the chief saturates of ram and human spermatozoa, and docosahexaenoic acid in the latter, were largely located in the choline and ethanolamine diacylphosphoglycerides.

摘要

公羊精子的主要个别磷酸甘油酯具有特定的脂肪酸组成，而人类精子的磷酸甘油酯含有相似的脂肪酸模式。两种物种精子磷酸甘油酯的多不饱和脂肪酸与饱和脂肪酸比例差异，与公羊精子缩醛磷脂中极高的多不饱和脂肪酸含量有关。公羊精子磷脂的主要不饱和脂肪酸二十二碳六烯酸集中在胆碱磷酸甘油酯中，而公羊和人类精子的主要饱和脂肪酸以及人类精子中的二十二碳六烯酸，大多位于胆碱和乙醇胺二酰基磷酸甘油酯中。
