Saccharides and Glycosides

Saccharides are organic compounds composed of carbon, hydrogen, and oxygen three elements.Saccharide compounds are closely related to human life. sugar is the main source of human energy. Saccharide is also closely related with drugs. For example, the patient needs glucose injection, dextran for plasma preparations; production of tablets commonly used starch as excipients; saccharides contained in some traditional Chinese medicine has a physiological activity, such as Poria Charges carbohydrate on mice sarcoma S100 which have a strong inhibition PUPS ; lentinan also strong inhibition of tumor. A glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body.
