Homochirality describes a geometric property of some materials that are composed of chiral units. Chiral refers to nonsuperimposable 3D forms that are mirror images of one another, as are left and right hands. A substance is said to be homochiral if all the constituent units are molecules of the same chiral form (enantiomer).
