WebDec 3, 2024 · An example of a pair of enantiomers is (S)- (+)-lactic acid and (R)- (-)-lactic acid. Alternatively, stereoisomers may be diastereomers, which aren't mirror images of each other. Diastereomers may contain chiral centers, but there are isomers without chiral centers and those that aren't even chiral. WebAbout more than half of the drugs currently in use are chiral compounds and near 90% of the last ones are marketed as racemates consisting of an equimolar mixture of two …

Heterometallic oligomers were prepared by connecting bis (β-diketonato)ruthenium (III) moieties to a labile metal ion through bis-β-diketonato bridging ligands [ 19, 21, 22, 52, 53 ]. The main attention is focused on the possibility of the …
WebChirality / k aɪ ˈ r æ l ɪ t iː / is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object.. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a mirror image of an achiral object, such as …
