Abstract

Analyses were made of lipids extracted from the spermatozoa of the sea-urchins, Diadema setosum, Arbacia lixula, Paracentrotus lividus and Clypeaster japonicus which belong to the order Diadematoida, Arbacioida, Echinoida and Clypeasteroida, respectively. Diadema setosum and A. lixula spermatozoa contained several kinds of phospholipids (phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine and caldiolipin), cholesterol and triglyceride. In addition to similar phospholipids, cholesterol and triglyceride, cholesterol-ester was also detected in C. japonicus spermatozoa. In contrast, lipids of P. lividus spermatozoa comprised phospholipids and cholesterol. In these species, the fatty acid composition of phosphatidylcholine, phosphatidylethanolamine and cardiolipin was of the unsaturated type for the most part, while phosphatidylserine and triglyceride, except in the case of P. lividus, comprised, to a considerable degree, saturated fatty acid.

基于棘刺类系统发育的四种海胆精子脂质成分比较

本文对海胆精子中脂质进行了分析。这5种海胆分别属于刺足目、刺足目、棘足目和刺足目，分别属于刺足目、刺足目。刚毛双足和黄颡鱼精子含有多种磷脂(磷脂酰胆碱、磷脂酰丝氨酸、磷脂酰乙醇胺和钙磷脂)、胆固醇和甘油三酯。除了类似的磷脂、胆固醇和甘油三酯外，在日本血吸虫精子中还检测到胆固醇酯。相比之下，卵黄精精子的脂质由磷脂和胆固醇组成。在这些物种中，磷脂酰胆碱、磷脂酰乙醇胺和心磷脂的脂肪酸组成大部分为不饱和类型，而磷脂酰丝氨酸和甘油三酯则有相当大的饱和脂肪酸组成，但lividus除外。
