| arachidonic acid | <biochemistry> An essential dietary component for mammals. The free acid is the precursor for biosynthesis of prostaglandins, thromboxanes, hydroxyeicosatetraenoic acid derivatives including leucotrienes and is thus of great biological significance. Within cells the acid is found in the esterified form as a major acyl component of membrane phospholipids (especially phosphatidyl inositol) and its release from phospholipids is thought to be the limiting step in the formation of its active metabolites.

| arachidonoylethanolamide synthase | <enzyme> Enzyme from rabbit cerebral cortex is coenzyme a- and ATP-independent Registry number: EC 3.5.1.- Synonym: arachidonylethanolamide synthase, anandamide synthase, anandamide amidase (26 Jun 1999) |
| arachidonyl transacylase | <enzyme> Catalyses CoA-independent transfer of arachidonate from phosphatidylcholine to lysoplasmenylethanolamine Registry number: EC 2.3.1.- Synonym: CoA-independent transacylase (26 Jun 1999) |

| Arachnia | A genus of nonmotile, nonsporeforming, facultatively anaerobic bacteria (family Actinomycetaceae) containing Gram-positive, non-acid-fast, branched, diphtheroid rods (0.2 to 0.3 by 3.0 to 5.0 um and longer). These organisms produce filamentous microcolonies. Their metabolism is fermentative. Primarily propionic and acetic acids are produced from glucose. Catalase is not produced. The cell wall contains diaminopimelic acid but not arabinose. These organisms are pathogenic for man, causing lacrimal canaliculitis and typical actinomycosis. The type species is Arachnia propionica. Arachnia propionica, a species causing lacrimal canaliculitis and typical actinomycosis; it is the type species of the genus Arachnia. Synonym: Propionibacterium propionicus. (05 Mar 2000) |

| arachnida | <zoology> One of the classes of Arthropoda. They have four pairs of legs, no antennae nor wings, a pair of mandibles, and one pair of maxillae or palpi. The head is usually consolidated with the thorax. The respiration is either by trancheae or by pulmonary sacs, or by both. The class includes three principal orders: Araneina, or spiders; Arthrogastra, including scorpions, etc.; and Acarina, or mites and ticks. Origin: NL, fr. Gr. Spider.
