    Abstract: A process for preparing glucose-1-phosphate from an alpha -glucan and orthophosphate using a phosphorylase immobilized onto an anion-exchange resin is disclosed. The anion-exchange resin used is a synthetic polymer resin into which an anion exchange group; a primary to quarternary ammonium group, a phosphonium group, or a sulfonium group, is introduced. This type of immobilized phosphorylase ensures (i) an effective utilization of phosphorylase, (ii) a higher reactivity of a higher absorbance of the phosphorylase to the resin, (iii) an excellent phosphorylase activity retention performance, and (iv) a higher physical strength of the resin.
