The cyclic structures for D-ribose and D-mannose are to be drawn. Concept introduction: Carbohydrates are polyhydroxy aldehyde and ketones , with an empirical formula C n ( H 2 O ) n . D-ribose is a pentose sugar which is composed of five carbon atoms, ten hydrogen atoms and five oxygen atoms bonded together in its structure and hence, known as aldopentose. On the other hand D-mannose is a sugar monomer of aldohexose consisting of six carbon atoms, twelve hydrogen atoms and six oxygen atoms. It is an C − 2 epimer of glucose. To determine: The cyclic structure of D-ribose and D-mannose
