A Modification of a Lactase Experiment by Use of Commercial Test Strips
Tammy J. Melton
Department of Chemistry, Middle Tennessee State University, Murfreesboro, TN 37132

Vol. 78 No. 9
p. 1243
Abstract
A modification of an experiment to monitor the action of the enzyme lactase on the substrate lactose is reported. Previous techniques employed chromatography or spectrophotometry to follow the increasing concentration of glucose as the lactose is hydrolyzed. In this paper the use of commercially available glucose test strips for home diabetic care is described as a new approach for determining the glucose concentrations.
Supplement
A handout for students is available.
