UNDERSTANDING MACROMOLECULES 100 points This assignment is a self-paced activity using the text to read about and draw the four macromolecules that will be on our next test. This assignment and the flashcards (see last slide) are due 9/15/13. You will be working on this in class AND at home The bold page numbers listed apply to the Campbell (BAT) text used in the classroom The (parentheses) page numbers listed apply to the STARR text at home.

Drawing Macromolecule Interactions (10 pts) Define Dehydration Synthesis aka Condensation Reaction p. 36: (STARR p.37) Draw and label the Dehydration Synthesis of a polymer Define Hydrolysis p. 36: (STARR p. 37) Draw and label Hydrolysis of a polymer

Carbohydrate (10 pts) p. 37-38 (STARR p.38) Draw the linear and ring forms of Glucose. Label. Draw the linear form of Fructose. Label. Draw the ring form of Maltose or Sucrose AND describe how it is made. Label.

Complex Carbohydrates (10 pts) p. 39 (STARR p.38-39) Define Polysaccharide. Draw a portion (8-10 segments) of a starch molecule. Label. Describe the function of glycogen, cellulose and starch. In what type of cells can you find glycogen, cellulose and starch?

Lipids (10 pts) p. 40-41 (STARR p.40-41) Draw the end result of a triglyceride (after dehydration of the fatty acid tail). Label the glycerol part and the Fatty Acids tails. You can simplify the hydrocarbon tail. Describe how unsaturated fatty acids and saturated fatty acids are different. Describe and tell the function and location of phospholipids, waxes and steroids (steroids are also called sterols).

Proteins (10 pts) p. 42-43 (STARR p.42-43) Draw the general structure of an amino acid. Label the amine group, carboxyl group and R group. Draw two amino acids joined by a peptide bond and label the parts. Describe 3 examples of Proteins function/classes.

Proteins Continued – Enzymes (10 pts) p. 42-43, 76-78 (STARR p.37, 44, 96, online) Define Denaturation Define Enzyme Draw a generic enzyme and label its parts – substrate, active site (online) Give an example of an enzyme and its action. (online)

Nucleic Acid (10 pts) p. 47 (STARR p.46-47) Draw and label a Nucleotide. Label the phosphate, sugar and nitrogen base. List and describe four types of nitrogen bases. What is the function of Nucleic Acids?

Vocabulary (30 pts) Generate flashcards note cards for the following terms. You will need to place the term on one side and the definition or picture on the opposite side. Make sure your definitions are 5-6 of your own words in length (in other words DON’T COPY OUT OF THE BOOK )
