How many carbons would a pentose sugar have
Weba single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules. Note the absence of the hydroxyl(-OH) group on the 2’ carbon in the deoxy-ribose sugar inDNAas … 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.
