| Novel imidazolium ionic liquids carrying anions of D-, L-, or omega-amino acids were prepared. The enzymatic enantioseparation of phenylalanine methyl ester in aqueous solutions of these ionic liquids was conducted as a model system. In general, these ionic liquids do not inhibit the enzyme activity; the enzyme enantioselectivity was observed close to that in [EMIM][OAc] solutions. However, higher activity and enantioselectivity were usually observed in ionic liquids based on D-amino acids than those based on L-amino acids. The reason is that D-amino acids are more kosmotropic than L-amino acids. |
