 * Organic || Inorganic ||
 * * molecules contain carbon and hydrogen bonds (hydrocarbs)
 * usually found in living things

Why is carbon so important? - carbon can bond to one or more other carbon atoms to form carbon skeletons and carbon rings - form single, double, or triple vonds || * molecules that do NOT have a carbon hydrogen bond
 * usually found in nonliving things (minerals, metals, salts, etc) ||

Life's large molecules classified into 4 categories:
 * Nucleic acids-** nucleotides


 * Lipids-** 3 fatty acids & glycerol


 * Proteins-** amino acids


 * Carbohydrates-** monosaccharides


 * Dehydration Synthesis-** removing (De) water (hydro) to add a monomer
 * Hydrolysis-** water (hydro) break down (lysis) --add water to break apart the molecule

buliding block: amino acids shape determines function --> sequence of amino acids
 * Enzymes-** protein: that speeds up chemical reaction
