The invention discloses a low molecular weight sulfated galactan, a preparation method and application thereof. The invention takes different types of red algae as raw materials, and prepares the low molecular weight sulfated galactan with different molecular weight sections by one-step extraction, degradation, separation and purification. The low molecular weight sulfated galactan of the invention can selectively inhibit PTP1B, improve glucose consumption of cells under insulin resistance conditions, improve insulin sensitivity, regulate energy consumption and maintain glucose homeostasis. Is expected to be developed into a medicament for preventing and/or treating type II diabetes and obesity or a food with the functions of reducing blood sugar, blood fat and weight, and has good market application prospect. |
