| carbon compounds, inorganic | Inorganic compounds that contain carbon as an integral part of the molecule but are not derived from hydrocarbons. (12 Dec 1998) |
|---|
| inorganic compounds | Those compounds lacking carbon but including carbonates and cyanides. Compounds not having the organised anatomical structure of animal or vegetable life. (05 Dec 1998) |
|---|---|
| carbon-carbon double bond isomerases | <enzyme> Enzymes that catalyze the shifting of a carbon-carbon double bond from one position to another within the same molecule. Registry number: EC 5.3.3 (12 Dec 1998) |
| carbon-carbon ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-carbon bond. These are the carboxylating enzymes and are mostly biotinyl-proteins. Registry number: EC 6.4 (12 Dec 1998) |
| carbon-carbon lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-carbon bond by means other than hydrolysis or oxidation. This subclass contains the decarboxylases, the aldehyde-lyases, and the oxo-acid-lyases. Registry number: EC 4.1 (12 Dec 1998) |
| chemistry, inorganic | A field of chemistry which pertains to chemical compounds or ions that do not contain the element carbon (with the exception of carbon dioxide and compounds containing a carbonate radical, e.g., calcium carbonate). (12 Dec 1998) |
| inorganic | Pertaining to substances not of organic origin. (18 Nov 1997) |
| inorganic acid | An acid made up of molecules not containing organic radicals; e.g., HCl, H2SO4, H3PO4. (05 Mar 2000) |
| inorganic chemicals | A broad class of substances encompassing all those that do not include carbon and its derivatives as their principal elements. However, carbides, carbonates, cyanides, cyanates, and carbon disulfide are included in this class. (12 Dec 1998) |
| inorganic chemistry | The science concerned with compounds not involving carbon-containing molecules. (05 Mar 2000) |
| inorganic compound | A compound in which the atoms or radicals consist of elements other than carbon and are typically held together by electrostatic forces rather than by covalent bonds; often are capable of dissociation into ions in polar solvents (e.g., H2O). Compare: organic compound. (05 Mar 2000) |
| inorganic dental cement | A dental cement consisting usually of metallic salts or oxides which, when mixed with a specific liquid, form a plastic mass that sets. (05 Mar 2000) |
| inorganic murmur | A cardiac murmur not associated with a significant heart lesion. Synonym: innocent murmur, inorganic murmur. (05 Mar 2000) |
| inorganic phosphate | inorganic orthophosphate |
| inorganic pyrophosphatase | A phosphohydrolase catalyzing hydrolysis of inorganic pyrophosphate to two orthophosphates. (05 Mar 2000) |
| active carbon dioxide | Activated carbon dioxide, a complex of N-carboxybiotin (biotin + CO2) and an enzyme; the form in which carbon dioxide is added to other molecules in carboxylations; e.g., to methylcrotonyl-CoA to form beta-methylglutaconyl in the catabolism of leucine, and to acetyl-CoA to form malonyl-CoA. See: acetyl-CoA carboxylase. (05 Mar 2000) |
