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.
Ribose is also a five-carbon sugar but found in RNA molecules. Ribose has a hydroxyl group in carbon 2, which resulting in an electrostatic negative charge for the molecule. Because of this charge, it repels the negatively charged phosphate group attached to the carbon 1 of the ribose, resulting uncoiled RNA molecules, unlike the DNA molecules. What is the difference between Deoxyribose and Ribose? DNA/RNA: Deoxyribose is the sugar found in DNA. Ribose is the sugar found in RNA. Structure: Deoxyribose lacks oxygen atom on carbon 2 of the sugar ring. Ribose has a hydroxyl group on carbon 2 of the sugar ring. Impact for the final structure:
