Abstract
A modification of an experiment previously developed for nutritional or introductory biochemistry courses quantifying the carbohydrate content of ripening banana is reported. Earlier investigations employed either chromatography or a colorimetric assay followed by spectroscopy to measure the increasing concentration of glucose as the banana ripens and included specialized and expensive biochemical equipment such as a refrigerated centrifuge and glass homogenizers. In this article the use of commercially available glucose test strips for home diabetic care is described as a new approach for determining the glucose concentrations in a ripening banana and common laboratory equipment has replaced a few specialized items.
Supplement
Instructions for the students and notes for the instructor are available.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.


C&EN CLICs

Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students. 


JCE Collections Available
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
