| racemization |
the transformation of one half of the molecules of an optically active compound into molecules which possess exactly the opposite (mirror-image) configuration, with complete loss of rotatory power because of the statistical balance between equal numbers of dextro- and levorotatory molecules. Cf. mutarotation.
