The object of the present invention is to provide glucosamine-containing glucans, modified products thereof and combinations thereof. The glucosamine-containing glucan of the present invention is a glucosamine-containing glucan in which the glucan has a plurality of non-reducing ends, and at least one glucosamine residue is linked to a branched chain α-1, Each of the 2 or more non-reducing ends of the 4-glucan is bound by an α-1,4-bond, but there is no Glucosamine residues are present where the dextran has a degree of polymerization of 15 or greater and 4x105 or less. The glucosamine-containing glucan of the present invention can be provided by allowing α-glucan phosphorylase to act on an aqueous solution containing branched α-1,4-glucan and glucosamine-1-phosphate. |
