The action of enzymes fascinated mankind long before they were rec ognized for the complex chemicals that they are. The first application of these remarkable compounds to produce ethanol by fermentation is lost to antiquity. Payer and Persoz (Ann. Chim. Phys. , 53, 73 (1833ii)) appear to have provided the first step toward understanding this com plex area when they reported the isolation of diastase in 1833. These workers showed that diastase could catalyze the hydrolysis of starches to sugars. Somewhat earlier Kirchhoff (Schwigger's Journal, 4, 108 (1812)) had shown that a small amount of dilute acid could hydrolyze a seemingly endless amount of starch to sugars. The genius of Berzelius recognized the commonality of these two observations in connection with a few other isolated observations and in 1834 coined the term catalysis to describe such actions. Professor Leibig was one of the giants of the chemical world in 1840. In addition to his own work, Liebig was training the world's next generation of chemists in his laboratory in Giessen. This cadre of chemists were very impressed by the master teacher so that is it only natural that Liebig's views should dominate with this next generation of chemists. Leibig was, in the 1830s and 1840s, developing his mastery of agricultural chemistry. The mechanism of putrefication was of great concern to Leibig, and he turned to the newly defined area of catalysis for an explanation.

The first four volumes of the series on 'Charged and Reactive Polymers' have been devoted to polymers in solution (Voh. I and II) or in gel and membrane forms (Vols. III and IV). In correlation with charges, other physical or chemical properties of macro molecules have been considered. Understanding of charge and hydrophobic effects is equally important for synthetic and biopolymers or their systems. Optically Active Polymers are related to problems of the same class, since optical activity is an inherent property of both natural macromolecules as well as a great variety of polymers synthesized in the Jast twenty years. Optical activity is a physical spectral property of chiral matter caused by asymmetrical configurations, conformations and structures which have no plane and no center of symmetry and consequently have two mirror image enantiomeric forms of inverse optical rotation. The racemic mixture of chiral enantiomers is optically inactive. The most common form of optical activity was first measured at a constant wavelength by the angle of rotation of linearly polarized light. More recently the measurements have been extended to the entire range of visible and attainable ultraviolet regions where electronic transitions are observed, giving rise to the ORD technique (Optical Rotatory Dispersion). The Cotton effects appear in the region of optically active absorption bands; outside of these bands the plain curve spectrum is also dependent on all the electronic transitions of the chromophores.
