Organic Molecules Comprise matter in living organisms Contain carbon and hydrogen Examples: carbohydrates, lipids, proteins Polymers (more complex, large molecules) are made from monomers (simple molecules) monomer polymer

Carbohydrates (carbo=carbon, hydr- = water) 2 H and 1 O (water) for every C Function: energy storage, cell structure Carbohydrate monomers are monosaccharides (simple sugars) -example: glucose Carbohydrate polymers are polysaccharides - longer term energy storage than monosaccharides Example: starch (in plants), glycogen in animals GLYCOGEN GLUCOSE

Lipids Function: long-term energy storage -are hydrophobic (literally “water-fearing”, meaning they don’t mix with water) -Examples: fats and oils Two types of fats: saturated and unsaturated
