Abstract
ASYMMETRIC adsorption of organic compounds on bio-polymers such as polysaccharides1–7, wool8,9 and casein9 has been reported, but the resulting optical activities of these were usually very low and the capacity for adsorption was very small. On the other hand, several studies of optical resolution by preferential crystallization have been reported (reviewed in ref. 10). Recently, DL-aspartic acid copper complex11, DL-aspartic acid, DL-glutamic acid, DL-asparagine and DL-glutamine12 have been resolved almost completely by the preferential crystallization method in our laboratory.
