tretinoin
Tretinoin: An important regulator of GENE EXPRESSION during growth and development, and in NEOPLASMS. Tretinoin, also known as retinoic acid and derived from maternal VITAMIN A, is essential for normal GROWTH; and EMBRYONIC DEVELOPMENT. An excess of tretinoin can be teratogenic. It is used in the treatment of PSORIASIS; ACNE VULGARIS; and several other SKIN DISEASES. It has also been approved for use in promyelocytic leukemia (LEUKEMIA, PROMYELOCYTIC, ACUTE).. retinoic acid : A retinoid consisting of 3,7-dimethylnona-2,4,6,8-tetraenoic acid substituted at position 9 by a 2,6,6-trimethylcyclohex-1-en-1-yl group (geometry of the four exocyclic double bonds is not specified).. all-trans-retinoic acid : A retinoic acid in which all four exocyclic double bonds have E- (trans-) geometry. | 2.49 | 2 | 0 | retinoic acid;

retinaldehyde
Retinaldehyde: A diterpene derived from the carotenoid VITAMIN A which functions as the active component of the visual cycle. It is the prosthetic group of RHODOPSIN (i.e., covalently bonded to ROD OPSIN as 11-cis-retinal). When stimulated by visible light, rhodopsin transforms this cis-isomer of retinal to the trans-isomer (11-trans-retinal). This transformation straightens-out the bend of the retinal molecule and causes a change in the shape of rhodopsin triggering the visual process. A series of energy-requiring enzyme-catalyzed reactions convert the 11-trans-retinal back to the cis-isomer.. all-trans-retinal : A retinal in which all four exocyclic double bonds have E- (trans-) geometry. | 2.06 | 1 | 0 | retinal;

beta Carotene: A carotenoid that is a precursor of VITAMIN A. Beta carotene is administered to reduce the severity of photosensitivity reactions in patients with erythropoietic protoporphyria (PORPHYRIA, ERYTHROPOIETIC).. provitamin A : A provitamin that can be converted into vitamin A by enzymes from animal tissues. | 2.71 | 3 | 0 | carotenoid beta-end derivative;

11-cis-retinal
Rhodopsin: A purplish-red, light-sensitive pigment found in RETINAL ROD CELLS of most vertebrates. It is a complex consisting of a molecule of ROD OPSIN and a molecule of 11-cis retinal (RETINALDEHYDE). Rhodopsin exhibits peak absorption wavelength at about 500 nm.. 11-cis-retinal : A retinal having 2E,4Z,6E,8E-double bond geometry. | 2.06 | 1 | 0 | retinal | chromophore;
