Deoxyribose versus
Ribose sugars
Ribose is
a single-ring pentose [5-C]
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 in DNA as compared with the ribose sugar in RNA.
