Asymmetric in such a way that the structure and its mirror image are not superimposable. Chiral compounds are typically optically active; large organic molecules often have one or more chiral centers where four different groups are attached to a carbon atom,

  1. Chiral is a Puzzle computer game for Mac OS by Ambrosia Software. Gameplay is built around the idea of linking atoms together to make molecules.
  2. (Chirality (Black Hole High episode)) The following is a list of episodes of the Discovery Kids' series Strange Days at Blake Holsey High which premiered on October 5, 2002 and ended on January 28, 2006. A total of 42 episodes were produced spanning 4 seasons.
  3. (Chirality (electromagnetism)) The term chiral describes an object, especially a molecule, which has or produces a non-superimposeable mirror image of itself. In chemistry, such a molecule is called an enantiomer or is said to exhibit chirality or enantiomerism. ...
  4. (Chirality (journal)) Chirality is a peer-reviewed scientific journal covering chiral chemistry in relation with physiology.
  5. (Chirality (knot theory)) In the mathematical field of knot theory, a chiral knot is a knot that is not equivalent to its mirror image. An oriented knot that is equivalent to its mirror image is an amphichiral knot, also called an achiral knot or amphicheiral knot. ...
  6. (Chirality (physics)) A chiral phenomenon is one that is not identical to its mirror image (see Chirality). The spin of a particle may be used to define a handedness (aka chirality) for that particle. A symmetry transformation between the two is called parity. ...
  7. Of an object that exhibits chirality, as in the left-handed and right-handed versions of a helix
  8. (chirality) The phenomenon, in chemistry, physics and mathematics, in which an object differs from its mirror image
  9. (chirality) When a molecule has a nonsuperimposable mirror image.  To imagine this, put your hands together.  Although they are mirror images, you can't put them right on top of each other so they are interchangable.  Well, normal people can't, anyway.
  10. (Chirality) handedness, the quality of having non-superimposable mirror images.
  11. (Chirality) A chemical term meaning handiness and being the cause for the spiral shape of DNA (double stranded helix) is explained in Here!
  12. (Chirality) property of non-surimposable entities (for example, the right hand and the left hand).
  13. (chirality) also known as handedness, used to distinguish between the two ways in which filaments break symmetry. As illustrated below, their barbs point in different directions.
  14. Having different left-handed and right-handed forms; not mirror symmetric; opposite of reflexible. The cube is not chiral; the snub cube is chiral as these two versions of the snub cube illustrate.
  15. Means "handedness" - A chiral or asymmetric molecule is one which can be distinguished from its mirror image. An example includes lactic acid.
  16. and full (or achiral) octahedral symmetry are the discrete point symmetries (or equivalently, symmetries on the sphere) with the largest symmetry groups compatible with translational symmetry. They are among the crystallographic point groups of the cubic crystal system.
  17. An asymmetric object or molecule.
