| phytanic acid | <chemical> 3,7,11,15-tetramethylhexadecanoic acid. A 20-carbon branched chain fatty acid. In phytanic acid storage disease (refsum disease) this lipid may comprise as much as 30% of the total fatty acids of the plasma. This is due to a phytanic acid alpha-hydroxylase deficiency. Chemical name: Hexadecanoic acid, 3,7,11,15-tetramethyl- (12 Dec 1998) |
| phytanic acid alpha-oxidase | <enzyme> May be the genetic defect in refsum's disease Registry number: EC 1.14.99.- Synonym: phytanic acid alpha-hydroxylase (26 Jun 1999) |
| phytanic acid storage disease | A genetic disorder of the fatty acid phytanic acid which accumulates and causes a number of progressive problems including polyneuritis (inflammation of numerous nerves), diminishing vision (due to retinitis pigmentosa), and wobbliness (ataxia) caused by damage to the cerebellar portion of the brain (cerebellar ataxia). (12 Dec 1998) |
| phytanoyl-CoA ligase | <enzyme> An acyl-CoA ligase found in peroxisomes of fibroblasts; it is distinct from palmitoyl-CoA ligase and lignoceroyl-CoA ligase Registry number: EC 6.2.1.- Synonym: phytanoyl-coenzyme a ligase (26 Jun 1999) |
| phytanoyl-coenzyme A hydroxylase | <enzyme> Mutations in gene pahx result in refsum disease; amino acid sequence given in second source; genbank af023462-3 Registry number: EC 1.14.- Synonym: phytanoyl-CoA hydroxylase, pahx protein, pahx gene product (26 Jun 1999) |
| phytanyl | A branched-chain hydrocarbon containing 20 carbon atoms, commonly found in the lipids of Archaea. (09 Oct 1997) |
| phytate | A salt or ester of phytic acid. (05 Mar 2000) |
| phytelephas | <botany> A genus of South American palm trees, the seeds of which furnish the substance called vegetable ivory. Origin: NL, fr. Gr. A plant + the elephant; also, ivory. Source: Websters Dictionary (01 Mar 1998) |
| phytic acid | Inositol hexaphosphate, found in plant cells, especially in seeds, where it acts as a storage compound for phosphate groups. (18 Nov 1997) |
| phytin | The calcium magnesium salt of phytic acid; a dietary supplement used to provide calcium, organic phosphorus, and myo-inositol. (05 Mar 2000) |
| phytivorous | Feeding on plants or herbage; phytophagous; as, phytivorous animals. Origin: Phyto- + L. Vorare to eat greedily. Source: Websters Dictionary (01 Mar 1998) |
| phyto- | <prefix> A combining form from Gr. Fyton a plant; as, phytochemistry, phytography. (29 Oct 1998) |
| phytoagglutinin | A lectin that causes agglutination of erythrocytes or of leukocytes. (05 Mar 2000) |
| phytoalexin | <protein> Toxic compounds produced by higher plants in response to attack by pathogens and to other stresses. Sometimes referred to as plant antibiotics, but rather non-specific, having a general fungicidal and bacteriocidal action. Very much analogous to an antibody response as production is triggered by elicitors. Examples include: pisatin, phaseolin. (14 Oct 1997) |
