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.
They have identical chemical structure except that ribose has a hydroxyl group (OH) on carbon 2, while deoxyribose is without an oxygenâ¦ on carbon 2 (H). Ribose is the sugar component of the structure of RNA (ribonucleic acid) and deoxyribose is the sugar component in DNA (deoxyribonucleic acid).
