NMR spin-spin couplings involving nuclei in the neighborhood of a carbonyl group. 3JCH couplings in α-substituted acetamides
(John Wiley & Sons Ltd, 2008-03)
In this work 3JCH spin-spin coupling constants (SSCCs) for the cis- and trans-conformers for α-X-acetamides (X = F, Cl, Br and CN) (1-4) were studied in detail since they were found to be notably different for both conformers. ...

Human Heme Oxygenase Oxidation of 5- and 15-Phenylhemes
(American Society for Biochemistry and Molecular Biology, 2004-10)
Human heme oxygenase-1 (hHO-1) catalyzes the O2- dependent oxidation of heme to biliverdin, CO, and free iron. Previous work indicated that electrophilic addition of the terminal oxygen of the ferric hydroperoxo complex ...
