Carbohydrates

All carbohydrates are made up of Carbon, Hydrogen and Oxygen atoms and have the general formula (CH2O)n. How many carbon atoms do you think triose, pentose and hexose have? **Monosaccharides:** glucose, fructose, galactose **Disaccharides:** sucrose, lactose **Polysaccharides:** chitin (insect exoskeletons and fungi cell walls), cellulose and glycogen
 * Carbohydrates** are molecules used to store energy. They are made up of single sugar units (**monosaccharides**, such as fructose or glucose) to form **disaccharides** (sucrose) and **polysaccharides** (starch, cellulose and glycogen). These molecules form via a "**condensation**" or "**hydrolysis**" reaction, in which a water molecule is released.

The molecule below shows how cellulose is formed (with thanks to Peter Razos):
