How many carbons in ribose sugar

WebThe purine and pyrimidine rings are both synthesized on the β-d-ribose ring (Figure 1.3). β-d-Ribose is a 5-carbon sugar with a hydroxyl group (-OH) on each carbon. Carbons 1 and 4 are joined into a five-member ring through the C4 hydroxyl oxygen. This ribose sugar is found in all RNA molecules. Figure 1.3. Structures of β-d-ribose and β ... 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.
