About This Lesson
This module from the U.S. Department of Energy focuses on the production of sugar from cornstarch. The first lesson relates glucose production from cornstarch to ethanol fuel production from corn stover. Another lesson uses a calculator based colorimeter interface from the Vernier Company to quantif More…y the hydrolysis of starch to sugar by salivary amylase. The third lesson again uses colorimetry but this time to measure starch hydrolysis by dilute sulfuric acid. Finally, we offer suggestions for using starch hydrolysis and colorimetry as a basis for student designed experiments.
