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.
This nucleotide contains the five-carbon sugar deoxyribose, a nitrogenous base called adenine, and one phosphate group. Together, the deoxyribose and adenine make up a nucleoside (specifically, a deoxyribonucleoside) called deoxyadenosine.
