The cause of death of coral reefs is bleaching, which substantially changes the molecular species profile of membrane lipids phosphatidylethanolamines (PE), phosphatidylinositols (PI), and phosphatidylserines (PS). The total contents of PE, PS, and PI were found to increase statistically significantly upon restoration of partially bleached soft coral Sinularia heterospiculata. The contents of PE ethers decreased during bleaching of S. heterospiculata because they could act as protection from oxidative stress. The PE molecular species profile of restored coral returned to the control values.

异刺珊瑚白化和随后恢复后磷脂分子形态的变化

珊瑚礁死亡的原因是白化，它极大地改变了膜脂磷脂酰乙醇胺 (PE)、磷脂酰肌醇 (PI) 和磷脂酰丝氨酸 (PS) 的分子种类特征。研究发现，部分白化的软珊瑚在恢复后，PE、PS 和 PI 的总含量显着增加。 PE醚的含量在S.heterospiculata漂白过程中下降，因为它们可以起到保护免受氧化应激的作用。恢复后的珊瑚的PE分子物种谱恢复到对照值。
