Fatty Acid | hydrocarbon chain often bonded to glycerol in a lipid |
Protein | polymer composed of amino acids inked by peptide bonds; is a polymer made up of monomers |
Amino Acid | polymer composed of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur |

Chemical Reaction | changes substances into different substances by breaking and forming chemical bonds |
Reactant | are the substances changed during a chemical reaction |
Product | are the substances made by chemical reaction |
Bond Energy | is the amount of energy that will break a bond between two atoms |
Equilibrium | condition in which reactants and products of a chemical reaction are formed at the same rate |
