On the heterogeneity of the mitochondrial C27-steroid 26-hydroxylase system
Journal of Lipid Research, 1976 Mitochondrial 26-hydroxylation of exogenous cholesterol, endogenous cholesterol, and 5β-cholestane-3α,7α,12α-triol was studied. 26-Hydroxylation of endogenous cholesterol was measured by mass fragmentography.

Specificity Determinants of CYP1B1 Estradiol Hydroxylation [PDF]
, 2013 Cytochrome P450 (P450)-catalyzed oxidation of the aromatic ring of estradiol can result in 2- or 4-hydroxylation. Which of these products is formed is biologically important, as the 4-hydroxylated metabolite is carcinogenic, whereas the 2-hydrox-ylated ...

Gas‐Selective Remote Plasma Engineering of WO3 Photoanodes for Solar Water Splitting
Advanced Materials Interfaces, EarlyView.Gas‐selective remote plasma treatment tunes the near‐surface defect chemistry of WO3 photoanodes without altering their bulk structure. Ar plasma generates the most oxygen‐vacancy‐rich surface and the highest W5+ content, delivering the strongest photocurrent.
