1. Different functions
Monosaccharides provide energy to the human body through decomposition. Blood sugar is the glucose that exists in the blood.
Disaccharides, naturally occurring free and functional sugars, are represented by lactose from mammals, trehalose from bacteria and insect blood, and sucrose from plants. These are used as energy sources for various organisms, or as material raw materials composed of organisms, and play an important role in the storage or transportation of necessary sugars.
Polysaccharides, in terms of immune regulation, can reduce the side effects of commonly used immunosuppressants, such as cytotoxicity, decreased anti-infection ability of the body, and inhibition of the reproduction of bone marrow hematopoietic cells.
2. Different classifications
Monosaccharides can be divided into triose, tetose, pentose, hexose, etc.
Disaccharides, sucrose, maltose, lactose, etc.
The broad classification of polysaccharides is divided into: homogeneous polysaccharides and heterogeneous polysaccharides.

3. Different characteristics
Monosaccharides Some chemical reactions proceed in ring structures, and some Proceed in an open chain structure.
Disaccharides can be crystalline, water-soluble or sweet. The monosaccharides that form the disaccharide determine these properties.
Polysaccharide is not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducing properties or mutarotation. Polysaccharides are also glycosides, so they can be hydrolyzed.
