How many carbons would a pentose sugar have

WebJul 4, 2024 · Since ribose has an aldehyde functional group, the ring closure occurs at carbon # 1, which is the same as glucose. See the graphic on the left. The exception is that ribose is a pentose, five carbons. Therefore a five membered ring is formed. The -OH on carbon #4 is converted into the ether linkage to close the ring with carbon #1. WebAug 25, 2024 · Pentose sugar has five carbon atoms. The main basis of nucleic acid is sugar. It is known as pentose sugar because it is pentagonal in shape with a carbon atom at its five corners. Examples of these sugars are deoxyribose sugar of DNA and ribose sugar of RNA. Its chemical formula is C₅H₁₀O₅ (2).

http://pratclif.com/biologie-moleculaire/dna/Sugars.html WebIn RNA, the carbon at the C-2 position is attached to a hydroxyl (OH) group. In DNA, the carbon at the C-2 does not contain this hydroxyl group; rather it is replaced by a hydrogen (H) atom. Therefore, the pentose ring in DNA is considered a deoxyribose (it is a deoxygenated five-carbon sugar ring).
