Protein and Nucleic Acid worksheet 1. Draw one amino acid. Label the amino group, the carboxy group, the alpha carbon. 2. Explain the four level of protein structure and draw a picture to illustrate it. Bonds that hold it Protein structure Explanation/ includes drawing together Primary Secondary Tertiary Quaternary 3. How does the characteristics of an amino acid (polar, non polar, acidic, basic) relate to the issue of tertiary and quaternary structure? 4. Draw a dipeptide and indicate the location of the peptide bond. Use R1 and R2 to indicate the R groups. 5. Indicate the level of protein structure (1, 2, 3, and/or 4) described in each of the following: helix pleated ______ and sheets ______ collagen and hemoglobin ______determined by the sequence of DNA bases ______ form stabilized hydrogen bonds ______ form stabilized hydrogen bonds, ionic bonds, hydrophobic interactions and disulfide bridges ______ globular proteins _____ interactions among several polypeptide chains ______ many enzymes ______ regular, repeated folding of the peptide chain ______ sequence of amino acids in a protein _____ the linear sequence of amino acids in the protein ______ not present in all proteins ____ caused by interactions between nonadjacent R groups ______ caused by interactions between polar regions of the C-N backbone ______ lost in the process of denaturation 6. What is an enzyme? What is its general function? 7. What does denaturation mean? 8. Explain how a protein is denatured in high temperatures.
