Abstract
By use of a spin label fatty acid, 5-doxylstearate, an increase in bulk membrane fluidity was observed after fertilization of two species of sea urchin eggs. Eggs partially activated by ammonia showed a similar effect. The data suggest that a structural change involving membrane lipids accompanies activation.
摘要
通过使用自旋标记脂肪酸5-脱氧硬脂酸盐，在两种海胆卵受精后观察到膜整体流动性增加。用氨部分激活的卵也表现出类似的效果。数据表明，激活过程伴随着涉及膜脂的结构变化。
