| stereochemical configuration | <chemistry> The arrangement of atoms in a molecule in three-dimensional space, especially with regard to the differences between enantiomers. The arrangements are specified in chemical formulas with the letters R, S, L, and/or D. In the R, S system, each asymmetric carbon atom is classified as R (for rectus, Latin for right) if the chemical groups attached to it have decreasing priorities in a clockwise direction, or S (for sinister, Latin for left) if the chemical groups attached to it have decreasing priorities in a counterclockwise direction, when the carbon atom in question is viewed along the bond of the chemical group with the lowest priority. Priorities are assigned to chemical groups according to the Cahn-Ingold Prelog priority rules (generally, the larger the group the higher the priority). L and D designations are given if the enantiomers have optical activity, that is, if they will rotate polarized light. The member of the pair which rotates polarized light clockwise is dextrorotatory, or D, and the member of the pair which rotates polarized light counterclockwise is levorotatory, or L (there is always one of each in every pair). This is also often referred to as handedness, where D is right-handed and L is lefthanded. (13 Nov 1997) |
| stereochemical formula | A chemical formula in which the arrangement of the atoms or atomic groupings in space are indicated. Synonym: spatial formula. (05 Mar 2000) |
| stereochemical isomerism | The phenomenon whereby compounds whose molecules have the same number and kind of atoms and the same atomic arrangement, but differ in their spatial relationships. (12 Dec 1998) |
| stereochemistry | <chemistry> Chemistry considered with reference to the space relations of atoms. Origin: Stereo + chemistry. Source: Websters Dictionary (01 Mar 1998) |
| stereocilium | <cell biology> Microfilament bundle supported projection, several microns long, from the apical surface of sensory epithelial cells hair cells) in inner ear: like a microvillus, but larger. It is stiff and may act as a transducer directly or merely restrict the movement of the sensory cilium which does have an axoneme). Also described on cells of pseudostratified epithelium of the epididymal duct. Recently, stereocilia have been referred to as stereovilli, a much better and less confusing name. (13 Nov 1997) |
| stereocinefluorography | An obsolete practice of recording on motion picture film the images obtained by stereoscopic fluoroscopy; three-dimensional views are obtained. (05 Mar 2000) |
| stereocolpogram | Picture taken with the stereocolposcope. (05 Mar 2000) |
