Did you know?
WebCompounds that rotate the plane of polarized light are termed optically active. Each enantiomer of a stereoisomeric pair is optically active and has an equal but opposite-in-sign specific rotation. Specific rotations are useful in that they are experimentally determined constants that characterize and identify pure enantiomers. WebIt is a way to identify optically active compounds. This is actually a very important topic in biochemistry. Many systems in the body perform functions with optically active compounds.
