The invention belongs to the field of marine medicines, and particularly relates to oligosaccharide containing D-galactose and L-galactose, derivatives thereof and application of the oligosaccharide and the derivatives thereof in medicines or health products for improving mitochondrial functions and preventing and treating insulin resistance-related diseases. The preparation method comprises the steps of taking red algae polysaccharide containing D-/L-galactose as a raw material, and degrading by a physical method, a chemical method, a biological enzyme method or any combination of the methods to prepare galacto-oligosaccharides with different polymerization degrees and derivatives thereof, wherein the molecular skeleton of the galacto-oligosaccharides contains D-galactose, L-galactose and derivatives thereof. The raw materials of the product are derived from the red algae polysaccharide, the product has the advantages of rich resources, simple preparation process, high safety, clear target spot, easy industrialization and the like, is used for improving the function of mitochondria, and has wide application prospect in the development fields of new medicines for preventing and treating insulin resistance and special medical foods for reducing blood sugar, blood fat, blood pressure and the like. |
