Reaction of Carbon Monoxide with Organo-metallic Compounds

The Use of Reaction Calorimetric Methods for Measuring Heats of Formation of Organo-metallic Compounds

The measurement of the heats of formation of organo-metallic compounds presents, usually, a difficult task to the experimental thermochemist. Thus the method of combustion in a conventional bomb-calorimeter, although it has been applied to a number of metallic alkyls in recent years! and yielded valuable results, is nevertheless not entirely satisfactory. The difficulty is that complete oxidati...

Antimicrobial action of carbon monoxide-releasing compounds.

Carbon monoxide (CO) is endogenously produced in the human body, mainly from the oxidation of heme catalyzed by heme oxygenase (HO) enzymes. The induction of HO and the consequent increase in CO production play important physiological roles in vasorelaxation and neurotransmission and in the immune system. The exogenous administration of CO gas and CO-releasing molecules (CO-RMs) has been shown ...

Ignition Kinetics of Carbon Monoxide - Oxygen Reaction

The Reaction of Cytochrome Oxidase with Carbon Monoxide*

The participation of molecular oxygen in biological oxidations is catalyzed by an enzyme which has been called-a variety of names starting with Atmungsfemzent by Warburg (18) to the currently employed term of cytochrome oxidase proposed by Keilin and Hartree (11). Presumably the enzyme functions by first combining with molecular oxygen and then becoming oxidized by it. As first shown by Warburg...

The reaction of hemoglobin Zürich with oxygen and carbon monoxide.

The present paper reports a spectroscopic and kinetic study of the reaction with oxygen and carbon monoxide of (a) the abnormal hemoglobin Zürich (beta 63, E7 His leads to Arg), (b) its isolated abnormal chains (beta ZH), and (c) a reconstituted hybrid containing cobalt instead of iron on the normal alpha chains (Co alpha)2-(Fe beta ZH)2. The abnormal beta ZH chains, isolated from hemoglobin Zü...
