Trioses contain three, pentoses contain five and hexoses six. Carbohydrates have many different functions and come in many different forms. Ribose and Deoxyribose are both pentose monosaccharides and are found in RNA and DNA. Glucose and Fructose are both hexose monosaccharides. Glucose is an important source of energy in respiration and Fructose is found in fruits. Sucrose is a disaccharide formed from Glucose and fructose....
