Much of the chemistry of glycosides is explained in the article on glycosidic bonds. For example, the glycone and aglycone portions can be chemically separated by hydrolysis in the presence of acid and can be hydrolyzed by alkali. There are also numerous enzymes that can form and break glycosidic bonds. The most important cleavage enzymes are the glycoside hydrolases, and the most important synthetic enzymes in nature are glycosyltransferases. Genetically altered enzym… WebJul 15, 2024 · It can undergo dehydration to form alkenes. This process is called the cholesterol dehydration reaction. Formation of glycosidic bonds. Glycoside or carbohydrate is a simple ring of sugar molecule which is formed of 5 or 6 carbon atoms. The interaction between two glycoside rings results in the formation of a covalent glycosidic …
WebFor example, when a glucose molecule is broken down, the glycosidic bonds are broken, bonds within water are broken and new bonds are made between the "disassembled" water and the atoms that were involved in the glycosidic bond.

WebIn formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an O-glycoside ), N- (a glycosylamine ), S- (a thioglycoside ), or C- (a C-glycoside) glycosidic bond. According to the IUPAC, the name " C -glycoside" is a misnomer ...
