What is the basic structure of an amino acid? What do they look like? - amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? - ionic, hydrophobic/nonpolar, ...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANSWER Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis.
