  1. Carbohydrate = hydrate of carbon.
  2. Hydroxyl group present.
  3. Aldehyde group or keto group may present.
  4. Carbohydrates are polyhydroxy aldehydes or ketose.
  5. Aldehyde group (-CHO) is generally terminal while keto group (> C = O) is commonly subterminal.
  6. Depending upon the presence of aldehyde or keto group, carbohydrates are called aldoses are ketoses.
  7. Carbohydrates contain Hydrogen and Oxygen in proportion as present in water.
  8. There are few exceptions -

                 Acetic acid (C2H4O2), Formeldehyde (CH2O), Lactic acid (C3H6O3)                         [Not Carbohydrate]
                 Deoxyribose sugar (C5H10O4), Ranose (C6H12O5), Glucosamine (C6H13ON)             [Carbohydrate]

  1. Empirical formula is Cn(H2O)n or (CH2O)n.
  2. Generally 3 elements present in carbohydrate as C, H & O.
  3. Some carbohydrates contain Nitrogen, Phosphorus and Sulphur.
  4. Carbohydrates are also named saccharides as they are formed of sugars.
  5. Carbohydrates that are water soluble & sweet in taste are called sugars.
  6. a & b - forms of sugar show isomerism.
