Abstract

1289549 Insolubilized enzymes; cellulose derivatives RANKS HOVIS McDOUGALL Ltd 3 Dec 1970 [18 Dec 1969] 61702/69 Headings C3A and C3H A water-insoluble enzyme preparation is made by reacting the enzyme dissolved or suspended in an aqueous solution with a cellulose carbonate. The enzyme may be #-glucosidase, trypsin, α-amylase, glucoamylase, or mouse liver or kidney extract. Cellulose carbonate is prepared by reacting cellulose suspended in dimethyl sulphoxide, p-dioxan and triethylamine with ethyl chloroformate.
