| phosphorus compounds | Inorganic compounds that contain phosphorus as an integral part of the molecule. (12 Dec 1998) |
|---|---|
| phosphorus isotopes | Stable phosphorus atoms that have the same atomic number as the element phosphorus, but differ in atomic weight. P-31 is a stable phosphorus isotope. (12 Dec 1998) |
| phosphorus metabolism disorders | Disorders in the processing of phosphorus in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
| phosphorus pentoxide | P2O5;the ultimate anhydride of orthophosphoric acid; a drying and dehydrating agent; corrosive. (05 Mar 2000) |
| phosphorus radioisotopes | Unstable isotopes of phosphorus that decay or disintegrate emitting radiation. P atoms with atomic weights 28-34 except 31 are radioactive phosphorus isotopes. (12 Dec 1998) |
| phosphorus, dietary | Phosphorus used in foods or obtained from food. This element is a major intracellular component which plays an important role in many biochemical pathways relating to normal physiological functions. High concentrations of dietary phosphorus can cause nephrocalcinosis which is associated with impaired kidney function. Low concentrations of dietary phosphorus cause an increase in calcitriol in the blood and osteoporosis. (12 Dec 1998) |
| phosphorus-32 | Radioactive phosphorus isotope; beta emitter with half-life of 14.28 days; used as tracer in metabolic studies and in the treatment of certain diseases of the osseous and haematopoietic systems. (05 Mar 2000) |
| phosphorus-33 | A radioactive isotope of phosphorus with a half-life of 25.3 days; used as a tracer in metabolic studies. (05 Mar 2000) |
| phosphorus-oxygen lyases | <enzyme> Enzymes that catalyze the cleavage of a phosphorus-oxygen bond by means other than hydrolysis or oxidation. Registry number: EC 4.6 (12 Dec 1998) |
| phosphoryl | 1. <chemistry> The radical PO, regarded as the typical nucleus of certain compounds. 2. <prefix> Prefix incorrectly used to signify a phosphate (e.g., phosphorylcholine) in place of the correct O-phosphono-or phospho-. Source: Websters Dictionary (21 Jun 2000) |
| phosphorylase | <enzyme> Enzyme that catalyses the sequential removal of glycosyl residues from glycogen to yield one glucose-1-phosphate per reaction. Its activity is controlled by phosphorylation (by phosphorylase kinase). (21 Jun 2000) |
| phosphorylase a | <enzyme> The phosphorylated and more active form of phosphorylase that functions as a regulatory enzyme during glycogen breakdown. The phosphate groups are hydrolytically removed by phosphorylase phosphatase to form phosphorylase b and orthophosphate. Registry number: EC 2.4.1.- (12 Dec 1998) |
| phosphorylase b | <enzyme> The relatively inactive form of phosphorylase that is reactivated to form phosphorylase a by phosphorylase kinase, which catalyses the enzymatic phosphorylation of the serine residues at the expense of ATP. Registry number: EC 2.4.1.- (12 Dec 1998) |
| phosphorylase kinase | <enzyme> The enzyme that regulates the activity of phosphorylase and glycogen synthetase by addition of phosphate groups. A large and complex enzyme, itself regulated by phosphorylation. Integrates the hormonal and calcium signals in muscle. (18 Nov 1997) |
| phosphorylase kinase phosphatase | <enzyme> Aspect of phosphoprotein phosphatase EC 3.1.3.16 Registry number: EC 3.1.3.- (26 Jun 1999) |

| phosphor- |
The special electrofluorescent coating used on the inside of a CRT screen that glows for a few milliseconds when struck by an electron beam. Because the illumination is so brief, it must be refreshed constantly to maintain an image.
