The chemical formula of many pentoses is C 5H 10O 5, and their molecular weight is 150.13 g/mol. Pentoses are very important in biochemistry. Ribose is a constituent of RNA, and the related molecule, deoxyribose, is a constituent … Zobacz więcej The aldopentoses are a subclass of the pentoses which, in the linear form, have the carbonyl at carbon 1, forming an aldehyde derivative with structure H–C(=O)–(CHOH)4–H. The most important … Zobacz więcej In the cell, pentoses have a higher metabolic stability than hexoses. A polymer composed of pentose sugars is called a pentosan. Tests for … Zobacz więcej The closed or cyclic form of a pentose is created when the carbonyl group interacts with a hydroxyl in another carbon, turning the carbonyl into a hydroxyl and creating an ether bridge –O– between the two carbons. This intramolecular reaction yields a Zobacz więcej
