Molecular formula :
nature : in its molecular structure with chiral centers (Yixian asymmetry) drugs. Due to its molecular polarization rotation of a different direction, the pair have each other mirroring the optical isomers, called enantiomers. The same chiral drugs on the different enantiomers not only have distinctly different pharmacological activity and pharmacokinetics of nature, but under certain conditions can be transformed into each other. Clinical used by the majority of the synthesis of chiral drugs as BNDADA administration, the chiral drug - and L-S-equal mixtures.
