过氧化胆固醇酯(CE-OOH)和过氧化磷脂酰胆碱(PC-OOH)是脂蛋白的主要初级氧化产物。CE-OOH存在于人和大鼠的血浆中,而PC-OOH则检测不到。这可能是由于血浆中PC-OOH的酶促(血浆谷胱甘肽过氧化物酶)和非酶促(载脂蛋白A和B-100)还原活性,以及高密度脂蛋白中卵磷脂胆固醇酰基转移酶将PC-OOH转化为CE-OOH的酶促作用所致。人血浆中CE-O(O)H的区域分布表明,自由基介导的链氧化是一个持续的过程,即使在健康的年轻人中也是如此。
Cholesteryl ester hydroperoxide (CE-OOH) and phosphatidylcholine hydroperoxide (PC-OOH) are the major primary oxidation products of lipoproteins. CE-OOH is present in human and rat plasmas while PC-OOH is undetectable. This is likely due to the enzymatic (plasma glutathione peroxidase) and the nonenzymatic (apolipoproteins A and B-100) reducing activities of PC-OOH in plasma, and to the enzymatic conversion of PC-OOH to CE-OOH by lecithin:cholesterol acyltransferase in high density lipoproteins. The regioisomeric distribution of CE-O(O)H in human plasma indicates that free radical-mediated chain oxidation is an ongoing process, even in healthy young individuals.
