Enantiomer and Recimic mixture

Enantiomer is a pair of optically active isomers which are the mirror image of each other. Two isomers of Lactic acid that rotates plane polarized light left by one and right by another. Enantiomers are stable, isolable. They are differ one from another by arrangement in space. Enantiomers are identical properties in all parameter without in terms of rotation of plane polarized light. Enantiomers rotate plane polarized light to the same degree, but in different direction. One rotates to right and others to left. The equal mixture of enantiomers are called racemic mixture. Racemic mixture do not rotate plane polarized light. Because one isomers activity to totate plane polarized light declined by the activity of other isomer in mixture.
