You are what you eat… Four major classes of macromolecules are found in cells: Carbohydrates Lipids Proteins Nucleic Acids All of these complex molecules begin with simple molecules-- called MONOMERS-- that bind together to make a POLYMER.

Carbohydrates Contain C (carbon), O (oxygen) and H (hydrogen) Soluable in water Most important carbohydrate is GLUCOSE, which we use in cellular respiration to make ENERGY

Carbohydrates (cont.) Monosaccharides/disaccharides are the simple sugars (monomers) Polysaccharides are the polymer-- created due to a chemical reaction called CONDENSATION-- removing a water molecule from between two simple sugars This reaction is reversible-- example is when sugar is digested in our guts due to HYDROLYSIS-- adding the water molecule back in.
