| retinaldehyde isomerase | <enzyme> Converts all-trans-retinal to 11-cis-retinal Registry number: EC 5.2.1.3 Synonym: retinal photoisomerase (26 Jun 1999) |

| retinaldehyde reductase | Alcohol dehydrogenase (NAD(P)+). (05 Mar 2000) |
| retinalite | <chemical> A translucent variety of serpentine, of a honey yellow or greenish yellow colour, having a waxy resinlike luster. Origin: Gr. Resin. Source: Websters Dictionary (01 Mar 1998) |
| retinasphaltum | <chemical> Retinite. Origin: Gr. Resin + asphalt. Source: Websters Dictionary (01 Mar 1998) |
| retinectomy | A surgical excision of a piece of the retina. (05 Mar 2000) |
| retinene | <chemical> A carotenoid constituent of visual pigments. It is the oxidised form of retinol which functions as the active component of the visual cycle. It is bound to the protein opsin forming the complex rhodopsin. When stimulated by visible light, the retinal component of the rhodopsin complex undergoes isomerization at the 11-position of the double bond to the cis-form; this is reversed in "dark" reactions to return to the native trans-configuration. Chemical name: Retinal (03 Jul 1999) |
| retinene-1 | <chemical> A carotenoid constituent of visual pigments. It is the oxidised form of retinol which functions as the active component of the visual cycle. It is bound to the protein opsin forming the complex rhodopsin. When stimulated by visible light, the retinal component of the rhodopsin complex undergoes isomerization at the 11-position of the double bond to the cis-form; this is reversed in "dark" reactions to return to the native trans-configuration. Chemical name: Retinal (03 Jul 1999) |
| retinene-2 | 3-Dehydroretinaldehyde;dehydroretinol with -CHO instead of -CH2OH at the terminal carbon of the side chain. Synonym: retinene-2, vitamin A2 aldehyde. (05 Mar 2000) |
| retinerved | <botany> Having reticulated veins. Origin: L. Rete a net + E. Nerve. Source: Websters Dictionary (01 Mar 1998) |
| retineum | <zoology> That part of the eye of an invertebrate which corresponds in function with the retina of a vertebrate. Source: Websters Dictionary (01 Mar 1998) |
| retinic | <chemistry> Of or pertaining to resin; derived from resin; specifically, designating an acid found in certain fossil resins and hydrocarbons. Origin: Gr. Resin. Source: Websters Dictionary (01 Mar 1998) |
| retinite | <chemical> An inflammable mineral resin, usually of a yellowish brown colour, found in roundish masses, sometimes with coal. Origin: Gr. Resin: cf. F. Retinite. Source: Websters Dictionary (01 Mar 1998) |
| retinitis | <ophthalmology> Inflammation of the retina. (05 May 1997) |
| retinitis pigmentosa | <ophthalmology> Disease caused by overactivity of the pigmented retinal epithelial cells, leading to damage and occlusion of photoreceptors and blindness. (18 Nov 1997) |
| retinitis proliferans | <ophthalmology, pathology> A disease of the small blood vessels of the retina of the eye. See: diabetic retinopathy. Origin: Gr. Pathos = disease (09 Oct 1997) |
