Figs. 3.4, 3.7, 3.13-3.16|Section 3.4 Saturday, December 01, 2007 2:18 PM Condensation Reactions (Dehydration reactions) - Loss of water, result in covalently bonded monomers, these reactions RELEASE a molecule of water for each covalent bond formed. MAIN: H20 is removed, and a covalent bond results between monomers. Hydrolysis Reaction - Digest polymers and produce monomers, Water is added, covalent bond between monomers is broken. Four Levels of Protein Structure: Primary - precise sequence of amino acids in a polypeptide chain, amino acid monomers are joined forming polypeptide chains. Determined by COVALENT BONDS. Secondary - Regular, repeated spatial patterns in diff regions of a polypeptide chain. Polypeptide chains may form Alpha helices or Beta pleated sheets. HYDROGEN BONDS Tertiary - polypeptide chain is bent at specific sites and then folded back and forth. 3D Shape. Covalent DISULFIDE BRIDGES, Hydrophobic, Van der Waals, Ionic bonds, hydrogen bonds. Quaternary - Two or more polypeptides assemble to form larger protein molecules.
