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.
In aqueous solution, deoxyribose primarily exists as a mixture of three structures: the linear form Hâ(C=O)â(CH 2)â(CHOH) 3 âH and two ring forms, deoxyribofuranose (C3'-endo), with a five-membered ring, and deoxyribopyranose (C2'-endo), with a six-membered ring.
