This worksheet is a sequel to my popular "Macromolecule Chart" and is similar in format. Students have already been introduced to how to draw the 4 macromolecules and now get more practice in making other biomolecules like glycerol, acetic acid, caffeine, ascorbic acid, citric acid, formaldehyde, histamine and penicillin. These were chosen for their size and for the fact that the kids have probably heard of them. These molecules can easily be made with the molecular model kits or paper molecules. Both chemistry and biology classes can use this worksheet when you are teaching about biochemistry. You can find a paper molecule set in my "Do-it-yourself Paper Molecular Model Set".
