| polycyclic hydrocarbons, aromatic | <chemical> A major group of unsaturated cyclic hydrocarbons containing two or more rings. The vast number of compounds of this important group, derived chiefly from petroleum and coal tar, are rather highly reactive and chemically versatile. The name is due to the strong and not unpleasant odour characteristic of most substances of this nature. Pharmacological action: carcinogens. (12 Dec 1998) |

| hydrocarbons, aromatic | Organic compounds composed exclusively of carbon and hydrogen. They are unsaturated hexagonal ring structures with a closed conjugated system of double bonds that gives them the characteristic chemical properties of the parent aromatic hydrocarbon, benzene. (12 Dec 1998) |
| basal metabolism | <biochemistry, biology> Heat production, or its measurement, of an organism at the lowest level of cell chemistry in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the heat production from an analysis of the end products of oxidation within the organism or from the amount of oxygen utilised. (27 Jun 1999) |
| calcium metabolism | A set of biochemical processes which act to keep the level of calcium in the blood at a constant level, with enough around to build bones and teeth. (09 Oct 1997) |
| carbohydrate metabolism | <biochemistry> The breakdown of starches and sugars into smaller units that can be used by the body for energy. (27 Sep 1997) |
| respiratory metabolism | The exchange of respiratory gases in the lungs, oxidation of foodstuffs in the tissues, and production of carbon dioxide and water. (05 Mar 2000) |
| metabolism | <biochemistry> The sum of all the physical and chemical processes by which living organised substance is produced and maintained (anabolism) and also the transformation by which energy is made available for the uses of the organism (catabolism). Origin: Gr. Metaballein = to turn about, change, alter (18 Nov 1997) |
| water of metabolism | The water formed in the body by oxidation of the hydrogen of the food, the greatest amount being produced in the metabolism of fat (about 117 g/100 g of fat). Synonym: water of combustion. (05 Mar 2000) |
| Crassulacean acid metabolism | <plant biology> Physiological adaptation of certain succulent plants, in which carbon dioxide can be fixed (nonphotosynthetically) at night into malic and other acids. During the day the carbon dioxide is regenerated and then fixed photosynthetically into the Calvin Benson cycle. This adaptation permits the stomata to remain closed during the day, conserving water. (18 Nov 1997) |
| primary metabolism | Metabolic processes central to most cells; e.g., biosynthesis of macromolecules, energy production, turnover, etc. (05 Mar 2000) |
| protein metabolism | Decomposition and synthesis of protein in the tissues. Synonym: proteometabolism. (05 Mar 2000) |
| xenobiotic metabolism | <biochemistry> This is the sum of the physical and chemical changes that affect foreign substances in living organisms from uptake to excretion. (09 Oct 1997) |
| secondary metabolism | Pathways producing specialised metabolic products that are not found inevery cell. (09 Oct 1997) |
| pyruvate metabolism, inborn errors | Hereditary disorders of pyruvate metabolism. They are difficult to diagnose and describe because pyruvate is a key intermediate in glycolysis, gluconeogenesis, and the tricarboxylic acid cycle. Some inherited metabolic disorders may alter pyruvate metabolism indirectly. Disorders in pyruvate metabolism appear to lead to deficiencies in neurotransmitter synthesis and, consequently, to nervous system disorders. (12 Dec 1998) |
| inborn error of metabolism | A genetic biochemical disorder of a specific enzyme that forms a metabolic block, e.g., phenylketonuria. (05 Mar 2000) |
