Examples of pentoses
In chemistry, a pentose is a monosaccharide (simple sugar) with five carbon atoms. 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 of … See more 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 example is See more 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 See more In the cell, pentoses have a higher metabolic stability than hexoses. A polymer composed of pentose sugars is called a See more WebFeb 19, 2024 · A nucleoside is a molecule with a pentose sugar linked to a nitrogenous base or glycosylamines. A nucleoside can also be defined as a nucleotide without a phosphate group attached to it. The nucleosides present in DNA contain a 2` – deoxy – D- ribose sugar and nucleosides in RNA contain D-ribose sugar. The main difference is seen at the ...
