THE OXIDATION OF CHOLESTEROL BY HYDROXYL RADICAL

Abstract— The oxidation of chblesterol by hydroxyl radical generated by 60Co y‐radiolysis of aqueous cholesterol dispersions or of dispersions saturated with N2O ave in low yields the products 38‐hydroxy‐cholest‐5‐en‐7‐one. the epimeric cholest‐5‐ene‐3β,7‐diols, 5,6α‐epoxy‐5α‐cholestan‐3β‐ol, 5.6β‐epoxy‐5β‐cholestan‐3,β‐ol, and 5α‐cholestane‐38,5,6β‐triol. Sterol hydroperoxides were not detected except in the radiolysis of dispersions saturated with oxygen.
