1. Carbohydrates are sugar molecules and are one of the most important nutrients found in food and drinks. When we consume food, the digestive system breaks down the carbohydrates into glucose which is then used as fuel by the body. (Carbohydrates: Types & Health Benefits, n.d.) 2. Glucose is an aldohexose, which means that it contains an aldehyde group and has 6 C atoms in the molecule. Besides the C involved in the aldehyde group, all the other C atoms contain an OH bonded to them. The presence of 5 OH groups and a carbonyl one makes the compound polar; moreover, all these groups can form hydrogen bonds with water.
