Chirality - Wikipedia

In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property. Web8. D- or L- Structure: Refers to whether the configuration at the chiral carbon furthest from the carbonyl group for a monosaccharide (for example, highest-numbered stereocenter is C5 of GLC or Fructose) in its open form in the Fischer projection resembles that for R-(+) or L-S-(-)-glyceraldehyde (2,3-dihydroxypropanal), respectively. bismuthate formula
