Kinetic Studies of Metalloporphyrins Bonding with Nitric Oxide

Interaction of Nitric Oxide with Catalase: Structural and Kinetic Analysis

We present the structures of bovine catalase in its native form and complexed with ammonia and nitric oxide, obtained by X-ray crystallography. Using the NO generator 1-(N,N-diethylamino)diazen-1-ium-1,2-diolate, we were able to generate sufficiently high NO concentrations within the catalase crystals that substantial occupation was observed despite a high dissociation rate. Nitric oxide seems ...

Monitoring of Serum Nitric oxide in Patients with Acute Leukemia

Nitric oxide (NO) is a molecule required for many physiological functions, produced from L-arginine by NO synthases (NOS). It is a free radical, producing many reactive intermediates that account for its bioactivity. Sustained induction of the inducible form of NOS (iNOS) in chronic inflammation may be mutagenic, through NO-mediated DNA damage or hindrance to DNA repair, and thus potentially ca...

Simple Kinetic Modeling of Selective Reduction of Nitric Oxide in Diesel Exhaust Over Cu-Zn/ZSM-5 Monolithic Catalyst

Kinetic studies of oxidative coupling of methane on samarium oxide

Kinetic behaviour of three samples of samarium oxide (cubic (Sm-1 ), monoclinic (Sm-3) and mixed cubic-monoclinic (Sm 2) ) were studied in the oxidative coupling of methane using a gradientless flow circulation system. The specific rate of C2product formation differed by a factor of 6-8 for Sm-1 and Sm-3. The specific activity for CO formation did not depend upon the crystal structure of samari...
