LESSON 2: CLASS AND CHARACTERISTICS OF MACROMOLECULES IN CELLS

Build a Carbohydrate

   


Explanation: Polysaccharides, a type of carbohydrate, consist of simple sugar monomers linked together by glycosidic linkages. Starting with the sugar molecule in the box above, build a 4-molecule polysaccharide. You will need to drag, possibly rotate, and drop the correct molecules to the correct positions to form glycosidic linkages. Remember that it is important that the sugar monomers are properly aligned to form the linkages. When you get the correct molecule in the correct spot to form a glycosidic linkage, a water molecule, indicating the condensation reaction, will be released.

 

Build a Carbohydrate

Drag, Rotate, and Drop the correct molecules into the shaded box to produce a 4-molecule polysaccharide.
 
Rotating molecules:
Use Alt-click (Windows) or Option-click (Macintosh) on an object to rotate it clockwise.
 
When SUCCESS! appears on the screen, you have successfully completed this task.
