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.
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
