carboxyl groupCOOH primary structure of a proteinThe first level of protein structure; polypeptide chain held together by peptide bonds secondary structure of proteinprotein structure stabilized by H bonds between atoms of the polypeptide backbone, creating helix and pleated sheets tertiary protein structure3D folding pattern of a protein due to side chain interactions (includes H and ionic bonds) quaternary structureThe fourth level of protein structure; the shape resulting from the association of two or more polypeptide subunits.hydrophobicR group contains C-C and C-H bonds; weak bonds that can be disrupted by change in temp. Cluster in the middle of a protein polarR group contains O-H, N-H, and S-H bonds.Chargedhave a + or a - charge ionic bondA chemical bond resulting from the attraction between oppositely charged ions.Disrupted by change in pH or by salts.Hydrogen bondscan only occur between polar, uncharged a.a. containing O or NH groups in their side chains. Disrupted by change in temp or pH.disulfide bondsStrong covalent bonds that can only be broken by chemical solutions (unique to cysteine) Triangle Gthe total free energy change that occurs during a reaction. Remains the same with or w/o an enzyme

EaEnergy of activation: the amt of energy needed to get a reaction started
