Chirality in organic chemistry refers to molecules that are not superimposable on their mirror images, much like hands. This property is pivotal in drug development, as enantiomers can have different biological effects. Chirality also influences the sensory properties of food and the structure of proteins. Advanced analytical techniques are used for chiral separation and characterization, addressing the challenges in real-time chiral analysis.
