Chiral meaning chemistry
WebThis term derives from the Ancient Greek word “cheir” (χείρ) for hand, to give a pictorial sketch of the chirality meaning. In chemistry, molecules that feature chirality can be spatially arranged into two specular, nonsuperimposable structures called enantiomers . Since enantiomeric pairs are the same chemical species, the different ... WebChirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon …

WebThe definition of chirality is the property of any object (molecule) being non-superimposable on its mirror image. The left and right hand are mirror images of each other, and they are not superimposable, so both the left hand and right hand are chiral. You can also find many other objects in daily life that show chirality as well. WebThe enantiomers of thalidomide were determined by direct resolution on a tribenzoyl cellulose column. Mean rate constants of chiral inversion of (+)-(R)-thalidomide and (-)-(S)-thalidomide in blood at 37 degrees C were 0.30 and 0.31 h-1, respectively. Rate constants of degradation were 0.17 and 0.18 h-1.
