One study suggests that low blood levels of vitamin D may increase risk for cognitive decline, while another study shows that consuming a diet rich in the antioxidant powerhouse vitamin E may help reduce the risk for dementia, including Alzheimer's disease.
Deoxyribose is a pentose sugar important in the formation of DNA, or deoxyribonucleic acid. Deoxyribose is a key building block of DNA. Its chemical structure allows for the replication of cells in DNA's double helix configuration. Deoxyribose contains 5 carbon atoms that are arranged to form the sugar's pentagonal shape.
Deoxyribose Sugar. Between the nitrogen-containing base and the phosphate group, which makes up the backbone of the DNA molecule, sits a sugar. It too has a ring form, composed of 5 atoms of carbon.he phosphate group is actually a triphosphate in DNA, which varies depending on which nitrogen-containing base it is binding to. The triphosphates include dATP, dGTP, dCTP, and dTTP, the second letter of the molecule name corresponding to whether it is binding to adenine, guanine, cytosine or thymine.
