Biochemistry Quiz on Amino Acids

Instructions: Answer each question that appears in the left hand frame by
clicking on a feature in the image that is shown in the right hand frame.
This quiz requires a Frame-enabled browser, such as Netscape Navigator 2.0.
See Netscape's home page for current information.

                               Start the Quiz.

Details:

  1. The questions:
        o There are 15 questions that cover all 20 amino acids.
        o Correct answers will take you to a comment on the amino acid.
        o Incorrect answers will give you two options:
             + Try again; or
             + Look at a "Hint".

  2. The images:
        o The amino acid structures are shown as their pH = 7 (zwitterionic)
          form.
        o The RasMol display modes used are: Ball & Stick, Sticks, and
          Spacefill.
          The atoms are shown with RasMol coloring:
          [Image]

             + Carbon: gray;
             + Oxygen: red;
             + Hydrogen: white;
             + Nitrogen: light blue;
             + Sulfur: yellow.
        o The coordinate files used are from Klotho.

  3. The links:
        o Links (colored red) within each question provide additional
          information or structures.
        o Links at the bottom of the question pages are to sites on the WWW
          where information is available on amino acids, e.g. Ê where
          structures can be displayed in RasMol and where various properties
          are compiled. From the question pages, these links will open from
          within the "Links & Glossary" frame. The same links are listed
          below; they will open a full page when clicked here.
