PROBLEM TO BE SOLVED: To provide a glucosamine-containing glucan, a modified material thereof, and a conjugate.SOLUTION: A glucosamine-containing glucan of the invention is the glucosamine-containing glucan in which a glucosamine residue is not present in any position except a nonreducing terminal of a branched α-1,4 glucan, though at least one of the glucosamine residue is linked by an α-1, 4 bond to each of two or more of the nonreducing terminals in a plurality of the nonreducing terminals of the branched α-1,4 glucan. The degree of polymerization of the glucan is 15 or more to 4×10or less. The glucosamine-containing glucan of the invention may be provided by making an α-glucan phosphorylase act on the branched α-1,4 glucan and glucosamine-1-phosphoric acid. |
