POLYSACCHARIDES FOR VISCOSITY MODIFICATION |
| 摘要 |
Compositions are disclosed herein comprising poly alpha-1,3-1,6-glucan with a weight average degree of polymerization (DPw) of at least 1000. This glucan polymer comprises at least 30% alpha-1,3 linkages and at least 30% alpha-1,6 linkages. Further disclosed are glucosyltransferase enzymes that synthesize poly alpha-1,3-1,6-glucan. Ether derivatives of poly alpha-1,3-1,6-glucan and methods of using such derivatives as viscosity modifiers are also disclosed. |

1. A composition comprising poly alpha-1,3-1,6-glucan, wherein
(i) at least 30% of the glycosidic linkages of said glucan are alpha-1,3 linkages, (ii) at least 30% of the glycosidic linkages of said glucan are alpha-1,6 linkages, (iii) said glucan has a weight average degree of polymerization (DPw) of at least 1000; and (iv) the alpha-1,3 linkages and alpha-1,6 linkages of said glucan do not consecutively alternate with each other. |
