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.
Ribose and deoxyribose are pentose. Ribose is also called ribofuranose because of the structural relationship to furane. The only structural difference between ribose and deoxyribose is the loss of an-OH group in position 2 in the ring.
