Bio-molecules Macro meaning large 4 macromolecules Bio-molecules Macro meaning large

Polymers… many monomers put together A monomer is a compound that can join other compounds to form polymers

Biological Polymers Proteins Carbohydrates Lipids Nucleic acids

Proteins Amino acids joined together 15% of our body Tissues, muscle, hair, nerves NH2 Amine group COOH Carboxyl group Both groups appear in all amino acids There are 20 amino acids Build and repair tissues in the body

Nucleic Acids Control cell reproduction DNA deoxyribonucleic acid RNA ribonucleic acid DNA stores genetic information RNA helps makes proteins inorganic

Carbohydrates C,H,O Sugars and starches Sugars are quick energy Starches are long lasting fuel Carbs are the bodys’ main source of energy

Lipids Fats and oils C H O Contain less Oxygen than carbs Cholesterol is a lipid Store 2x the energy as carbs
