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.
A deoxyribose is different from a ribose because it is missing one oxygen atom and does not contain the alcohol group. The absence of these parts and the missing 2' hydroxyl group makes it possible for the DNA to take its well known double helix shape. This also makes it possible for the DNA strands to be compacted in the core of the cells.
