WebThe chiral feature is a critical factor for the efficacy and safety of many therapeutic agents. At present, about 57% of marketed drugs are chiral drugs and about 99% of purified natural products are chiral compounds. There has been a tremendous potential of functional microorganisms and biocatalyst … WebChirality (chemistry) The term chiral (pronounced /ˈkaɪɹ (ə)l̩/) is used to describe an object that is non-superimposable on its mirror image. Human hands are perhaps the most universally recognized example of chirality: the left hand is a non-superimposable mirror image of the right hand: no matter how the two hands are oriented, it is ...
