As the name implies, deoxyribose is a deoxygenated sugar, meaning it is derived from ribose sugar by the loss of an oxygen atom. 's' : ''}}. Ribose, which is a pentose sugar just like deoxyribose, is important for RNA, a molecule that plays a key role in the expression of human genes. In terms of chemical structure, deoxyribose is constructed of five carbon, ten hydrogen, and four oxygen (C5H10O4). Hydroxyl groups are attached to three of the carbons. Deoxyribose contains 5 carbon atoms that are arranged to form the sugar's pentagonal shape. Ribose forms a five member ring composed of four carbon atoms and one oxygen. In 1983, H.G. In conclusion, RNA is a polymer with a ribose and phosphate backbone and 4 different bases: adenine, cytosine, guanine, and uracil, whereas DNA is a long polymer with a deoxyribose and phosphate backbone and four different bases: adenine, cytosine, guanine, and thymine. A nucleoside has two parts: a pentagonal sugar (deoxyribose) and a nitrogenous base (in color). As a member, you'll also get unlimited access to over 83,000 Unlike in ribose sugar, deoxyribose lacks an oxygen atom on carbon 2 of the sugar ring. What Is Deoxyribose? An explicit range of sugar conformations is associated with A-, B-, and Z-form DNA duplexes and, within a determined family (i.e., B-form DNA), local structural variations correlate with the specific sugar pucker. As a result, DNA is more stable. Your Health Remedy is a website for those who aspire to improve themselves and their life, as well as contribute to making the world a better place to live.
