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.
The sugar is the pentose sugar known as deoxyribose (the D â¦ in DNA). The deoxy just means that it is missing an oxygen group compared ribose. The base is what makes up the language of DNA. There are four possible bases, adenine, thymine, cytosine, and guanine.
