二十碳四烯酸

血小板中环氧酶和脂氧酶作用于花生四烯酸代谢系统，可产生形成血栓的血栓烷A2（TXA2）及引起过敏性疾病的12－羟基二十碳四烯酸（12－HETE）。

In platelets , cyclooxygenase and lipoxygenase catalyze the initial reactions for the formation of two major arachidonic acid metabolites , thromboxane B 2 ( TXB 2 ), 12 hydroxy 5,8,10,14 eicosatetraenoic acid ( 12HETE ) .
