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.
Compare Ribose and Deoxyribose Structures: The presence or absence of the-OH group on carbon (#2) is an important distinction between ribose and deoxyribose. Ribose has an alcohol at carbon # 2, while deoxyribose does not have the alcohol group. See red-OH and H in the structures on the left.ibose. Ribose and its related compound, deoxyribose, are the building blocks of the backbone chains in nucleic acids, better known as DNA and RNA. Ribose is used in. NA and deoxyribose is used in. NA.
