Dehydrogenation is a chemical reaction that involves the elimination of hydrogen chem H 2 . It is the reverse process of hydrogenation . Dehydrogenation reactions may be either large scale industrial processes or smaller scale laboratory procedures. Classes of the reaction There are a variety of classes of dehydrogenations Aromatization Six membered alicyclic compound alicyclic rings can be aromatized in the presence of hydrogenation catalysts, the elements sulfur and selenium , or quinone s such as 2,3 Dichloro 5,6 dicyano 1,4 benzoquinone DDQ . Oxidation The conversion of alcohols to ketones or aldehydes can be effected by metal catalysts such as copper chromite . In the Oppenauer oxidation , hydrogen is transferred from one alcohol to another to bring about the oxidation. Dehydrogenation of amines amines can be converted to nitriles using a variety of reagents , such as Iodine pentafluoride chem IF 5 . Dehydrogenation of paraffins and olefins paraffins like n pentane and isopentane can be converted to pentene and isoprene using chromium III oxide as a catalyst at 500 degree C. Dehydrogenation converts saturated fats to unsaturated fats . Enzymes that catalyze dehydrogenation are called dehydrogenases . Dehydrogenation processes are used extensively to produce styrene in the fine chemicals , oleochemicals , petrochemicals , and detergents industries. Feed stocks Likely feed stocks to be used in this dehydrogenation process include hydrocarbons, such as Ethylbenzene Methanol Butane Butene Cyclohexane Inorganic compounds, such as hydrogen sulfide or hydrogen iodide , are also used.

Mixed function oxidase is the name of a family of oxidase enzymes that catalyze a reaction in which each of the two atoms of oxygen in O sub 2 sub is used for a different function in the reaction. ref MeshName Mixed Function Oxygenases ref Oxidase is a general name for enzymes that catalyze oxidations in which molecular oxygen is the electron acceptor but oxygen atoms do not appear in the oxidized product. Often, oxygen is reduced to either water cytochrome oxidase of the mitochondrial electron transfer chain or hydrogen peroxide dehydrogenation of fatty acyl CoA in peroxisome s . Most of the oxidases are flavoprotein s. The name mixed function oxidase indicates that the enzyme oxidizes two different substrate simultaneously. Desaturation of fatty acyl CoA in vertebrates is an example of the mixed function oxidase reaction. In the process, saturated fatty acyl CoA and NADPH are oxidized by molecular oxygen O sub 2 sub to produce monounsaturated fatty acyl CoA, NADP sup sup and 2 molecules of water.

Isomers From 1,4 naphthoquinone Due to the symmetry of the parent quinone, there are only nine distinct isomers of dihydroxy 1,4 naphthoquinone 2,3 Dihydroxy 1,4 naphthoquinone . symmetric 2,5 Dihydroxy 1,4 naphthoquinone . 3,8 2,6 Dihydroxy 1,4 naphthoquinone . 3,7 2,7 Dihydroxy 1,4 naphthoquinone . 3,6 2,8 Dihydroxy 1,4 naphthoquinone . 3,5 5,6 Dihydroxy 1,4 naphthoquinone . 7,8 5,7 Dihydroxy 1,4 naphthoquinone . 6,8 5,8 Dihydroxy 1,4 naphthoquinone naphthazarin . ref name khalafy J.

CysG synthesizes sirohaem from uroporphyrinogen III via reactions which encompass two branchpoint intermediates in tetrapyrrole biosynthesis , diverting flux first from protoporphyrin IX biosynthesis and then from cobalamin vitamin B12 biosynthesis. CysG is a protein dimer dimer . Its dimerisation region is 74 amino acids long, and acts to hold the two structurally similar protomers held together asymmetrically through a number of salt bridges across wikt complementary complementary residues within the dimerisation region. ref name pmid14595395 cite journal author Stroupe ME, Leech HK, Daniels DS, Warren MJ, Getzoff ED title CysG structure reveals tetrapyrrole binding features and novel regulation of siroheme biosynthesis journal Nat.
