Anwendungsbeispiele Englisch
  • By studying the changes in optical activity, researchers may better understand cellular processes.
  • In ordered structures lacking two-fold rotational symmetry, optical activity, including differential transmission (and reflection) of circularly polarized waves also depends on the propagation direction through the material.
  • In 1818, Seebeck discovered the optical activity of the solutions of sugar.
  • For example, a ruby from Burma will have definite internal and optical activity variance from a Thai ruby.
  • In 1874 he announced his theory outlining the relationship between molecular structure and optical activity.

  • Chiral synthesis is built on a combination of stereospecific transformations (for the interconversion of existing stereocenters) and stereoselective ones (for the creation of new stereocenters), where also the optical activity of a chemical compound is preserved.
  • The only tool for analysing enantiomers was optical activity using a polarimeter, a method which provides no structural data.
  • Such optical activity was described in adamantane in 1969 with the four different substituents being hydrogen, bromine and methyl and carboxyl group.
  • In 1874, he accounted for the phenomenon of optical activity by assuming that the chemical bonds between carbon atoms and their neighbors were directed towards the corners of a regular tetrahedron.
  • Optical activity is measured using a polarized source and polarimeter.

  • Erythritol is an organic compound, a four-carbon sugar alcohol (or polyol) with no optical activity, used as a food additive and sugar substitute.
  • In 1815, Jean-Baptiste Biot's observation of optical activity marked the beginning of organic stereochemistry history.
  • It is the simplest of all ketoses and has no chiral center or optical activity.
  • It is the only ketose with no optical activity. All monosaccharide ketoses are reducing sugars, because they can tautomerize into aldoses via an enediol intermediate, and the resulting aldehyde group can be oxidised, for example in the Tollens' test or Benedict's test.
  • In 1843, Louis Pasteur discovered optical activity in paratartaric, or racemic, acid found in grape wine.

  • On heating the reaction to 0 °C the optical activity is lost.
  • " by conventional rules (independently of their optical activity).
  • The lack of optical activity is due to the polymerization of lignin which occurs via free radical coupling reactions in which there is no preference for either configuration at a chiral center.
  • Pasteur determined that optical activity related to the shape of the crystals, and that an asymmetric internal arrangement of the molecules of the compound was responsible for twisting the light.
