| 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) |
| inborn errors of metabolism | Term coined by A. Garrod in 1908 applying to heritable disorders of biochemistry. Examples include albinism, cystinuria (a cause of kidney stones) and phenylketonuria (pku) are a few of the hundreds of inborn errors of metabolism. (12 Dec 1998) |
| intermediary metabolism | Enzyme-catalysed processeswithin cells that extract energy from nutrientmolecules and use that energy to construct cellular components. (09 Oct 1997) |
| oxidative metabolism | Respiration in the biochemical sense. (18 Nov 1997) |
| electrolyte metabolism | The chemical changes that various essential minerals (e.g., sodium, potassium, calcium, magnesium) undergo in the tissues. (05 Mar 2000) |
| energy metabolism | Those metabolic reactions whose role is to release or to provide energy. (05 Mar 2000) |
| fat metabolism | Oxidation, decomposition, and synthesis of fats in the tissues. (05 Mar 2000) |
