Vitamin E and Alzheimer's Risk. A second study in the July issue of the Archives of Neurology shows that eating foods rich in vitamin E may help lower risks of developing dementia and Alzheimer's disease.
Ribose and Deoxyribose. The 5-carbon sugars ribose and deoxyribose are important components of nucleotides, and are found in RNA and DNA, respectively. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms. A combination of a base and a sugar is called a nucleoside. Ribose, found in RNA, is a normal sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name deoxy).
Deoxyribonucleic acid is a phosphorous containing compound, as opposed to a protein which is a sulphur containing compound and the name refers to the chemicals that it consists of. Deoxyribose-This is a sugar, known chemically as a pentose, a five-carbon sugar. Nucleic-Refers to the location of DNA inside the nucleus. The molecule was originally called 'nuclein' by Frederick Miescher, the man who discovered DNA in 1869. Acid-It is a phosphoric acid.
