Chiral

(Science: chemistry) a term used to describe a molecule which, in a given configuration, cannot be superimposed on its mirror image.

this is in contrast to achiral molecules which can be superimposed on their mirror images. The two mirror image versions of the molecule are known as levo (left-handed), abbreviated L, or dextro (right handed), abbreviated D, depending on which way they rotate polarized light.

... the position of the light source. Amino acids are mostly L compounds (from levo, or left). Compounds that rotate plane polarized light contain chiral centers. http://en.wikipedia.org/wiki/Optical_activity http://en.wikipedia.org/wiki/Chirality_(chemistry)

why Sugar got sweet taste?

@swatkat yup, chiral molecules and optical activity..:lol: @Andrew I think that swatkat asked is about sugar, not a synthesized sweeteners...so, I would go to fructose..:lol: At least, that's what I catch from your previous post..:D
