1. A product comprising a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with at least one of:
a) at least one sulfate group;
b) at least one sulfonate group;
c) at least one thiosulfate group; or
d) a combination thereof;
wherein the polysaccharide is poly alpha-1,3-1,6-glucan, wherein (i) at least about 30% of the glycosidic linkages of the poly alpha-1,3-1,6-glucan are alpha-1,3 linkages, (ii) at least about 30% of the glycosidic linkages of the poly alpha-1,3-1,6-glucan are alpha-1,6 linkages, (iii) the poly alpha-1,3-1,6-glucan has a weight average degree of polymerization (DPw) of at least about 10; and (iv) the alpha-1,3 linkages and alpha-1,6 linkages of the poly alpha-1,3-1,6-glucan do not consecutively alternate with each other.
