ketene
ketene: structure. ketene : Carbonyl compounds where the C=O bond is conjugated to an alkylidene group. | 2.1 | 1 | 0 | ketene | |
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;
vitamin A | gap junctional intercellular communication inhibitor;
human metabolite;
mouse metabolite |
stilbenes
Stilbenes: Organic compounds that contain 1,2-diphenylethylene as a functional group.. trans-stilbene : The trans-isomer of stilbene. | 2.1 | 1 | 0 | stilbene | |
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;
human metabolite;

silicon
Silicon: A trace element that constitutes about 27.6% of the earth's crust in the form of SILICON DIOXIDE. It does not occur free in nature. Silicon has the atomic symbol Si, atomic number 14, and atomic weight [28.084; 28.086]. | 2.11 | 1 | 0 | carbon group element atom;
metalloid atom;
