How many carbons in ribose sugar

WebThe three-carbon sugars formed when the unstable sugar breaks down are different from each other. Only one—glyceraldehyde-3-phosphate—can enter the following step. However, the unfavorable sugar, DHAP \text{DHAP} DHAP start text, D, H, A, P, end text, can be easily converted into the favorable one, so both finish the pathway in the end. WebThe deoxyribose sugar in DNA is a pentose, a five-carbon sugar. Four carbons and an oxygen make up the five-membered ring; the other carbon branches off the ring. Similar to the numbering of the purine and pyrimidine rings (seen in ), the carbon constituents of the sugar ring are numbered 1'-4' (pronounced "one-prime carbon"), starting with the ...
