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).
DNA contain the deoxyribose sugar. Other differences may include; DNA is double stranded while RNA is single stranded DNA contain the base thymine while RNA contain the base Uracil in place of thymine.he sugar present in RNA molecule is ribose and in DNA molecule it is deoxyribose. Deoxyribose is the same as ribose, except that the former has one more OH. Deoxyribose sugar is less reactive because of C-H bond and ribose sugar is more reactive because of C-OH bonds.
