chiralitystä
Chirality is a property of an object or molecule that cannot be superimposed on its mirror image. Think of your hands: your left hand is a mirror image of your right hand, but you cannot perfectly align them no matter how you twist or turn them. Objects that possess this "handedness" are called chiral.
In chemistry, chirality is a fundamental concept, particularly when discussing molecules. A molecule is chiral if
Enantiomers have identical physical properties like melting point and boiling point, but they can behave differently
The biological world is replete with chiral molecules, and often only one enantiomer is biologically active.
