Dictionary » O » Oxidizes



(Science: chemistry) To combine with oxygen, or subject to the action of oxygen, or of an oxidizing agent. Specifically:

To combine with oxygen or with more oxygen; to add oxygen to; as, to oxidize nitrous acid so as to form nitric acid.

To remove hydrogen from (anything), as by the action of oxygen; as, to oxidize alcohol so as to form aldehyde.

To subject to the action of oxygen or of an oxidizing agent, so as to bring to a higher grade, as an -ous compound to an -ic compound; as, to oxidize mercurous chloride to mercuric chloride.

In certain cases to oxidize is identical with to acidify; for, in nearly all cases, the more oxygen a substance contains the more nearly does it approximate to acid qualities; thus, by oxidation many elements, as sulphur, nitrogen, carbon, chromium, manganese, etc, pass into compounds which are acid anhydrides, and thus practically in the acid state.

Origin: Oxidized; Oxidizing.

Bacterias in Nitrification

... also read some contradicting research articles which stated that instead of Nitrobacter a new type called Nitrospira are the ones who actually oxidizes Nitrite to Nitrate. Need opinions from the experts whether this is true or not.

an odd-appearing Michaelis-Menten curve

Hi all, I have been assaying an enzyme that oxidizes OH groups and reduces NADP+. The assay is based on the absorbance of NADPH at 340 nm. The problem is that the graph of reaction rate versus substrate concentration looks like an exponential curve ...
