First step: Unzip it 2. Deoxyribose is a pentose sugar important in the formation of DNA, or deoxyribonucleic acid. Deoxyribose contains 5 carbon atoms that are arranged to form the sugar's pentagonal shape. Think of deoxyribose as having an open spot that can take on an atom; something ribose cannot do because of its additional oxygen atom. Compared to other pentose sugars, deoxyribose is considered a modified sugar due to the fact that it only has four oxygen atoms. Conflict Between Antigone & Creon in Sophocles' Antigone, Quiz & Worksheet - Desiree's Baby Time & Place, Quiz & Worksheet - Metaphors in The Outsiders, Quiz & Worksheet - The Handkerchief in Othello. 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. Deoxyribose was synthesized in 1935, but was not isolated from DNA until 1954 (Encyclopædia Britannica, 1998). Similar to ribose, deoxyribose is a chiral molecule, a property of asymmetry. The difference between deoxyribose and ribose is that deoxyribose has a hydrogen (-H) attached to the second (2′) carbon of the sugar ring, while ribose has a hydroxyl group (-OH) attached to this carbon.
