Utilizing density functional theory calculations, we demonstrate that SCD1 employs a mechanism unknown previously in other NHFe2 enzymes, which involves the binding of O-2/water leading to Fe-A(II)-(OH)-O-center dot + Fe-B(II)-(OOH)-O-center dot, the addition of H+/e forming Fe-A(...
Learn about alkane, alkene, and alkyne - types of hydrocarbons. See their structures and properties. Further, explore what makes them different...
but common in nature. Iron oxygenases activate the O–O bond of dioxygen to perform oxidation of alkane and alkenes moieties with outstanding levels of regio-, chemo- and stereoselectivity. Along a bioinspired approach, iron coordination complexes which mimic structural and reactivity aspects of the ...

13.The name of an alkene is derived from the name of the alkane with the same number of carbon atoms. 14.The electrolytic titration method was compared with the inverse titration method in this paper for the accuracy of the measuring alkene. ...
A Possible Mechanism of Alkene/Alkane Production Alkene/alkane ratios have been used extensively as indicators of oil-shale retorting conditions. Jacobson, Decora, and Cook ( 1 ) developed a retorting index that relates the ethene/ethane ratio to temperature, and Campbell and coworkers... AK ...
