D. Caruso et al., IDENTIFICATION OF BETA-HYDROXY-5-ALPHA-CHOLEST-6-ENE-5-HYDROPEROXIDE IN HUMAN OXIDIZED LDL, Chemistry and physics of lipids, 79(2), 1996, pp. 181-186
Oxidized LDL exhibits cytotoxic activity towards endothelial cells, wh
ich is thought to be mediated by the products derived also from choles
terol oxidation, mainly involving the B-ring. By LC-PB-EI-MS and EI-MS
/MS analysis. we have identified 3 beta-hydroxy-5 alpha-cholest-6-ene-
5-hydroperoxide among the cholesterol oxidation products in LDL incuba
ted with micromolar concentrations of copper ions.
