花生四稀酸(arachidonic acid,AA)是含二十碳的不饱和脂肪酸,在环氧化酶(cyclooxygenase,COX)和脂氧化酶(lipoxygenase,LOX)作用下代谢产生前列腺素(PGs)、羟基二十碳四稀酸(HETE)和白三稀(LTs)等类花生酸(eicosanoids)物质。现已证明类花生酸物质在肿瘤的发生
Arachidonic acid (AA) is a twenty-carbon unsaturated fatty acid which is metabolized by cyclooxygenase (COX) and lipoxygenase (LOX) to produce prostaglandins (PGs) Eicosanoids such as HETE and LTs. It has now been demonstrated that eicosanoids occur in tumors
