Experimental Themes for Extension Lectures (6)

“The Works of Detergents Containing Proteinases”

Abstract

Amylases, lipases, cellulases, and proteinases (peptidases) have been used for the enzymes added in detergents. Activity of added enzymes in detergents is utilizable to lead new themes of extension lectures. This research describes proteinases added in detergents. Proteinases hydrolyze proteins to small proteins, peptides, or amino acids. The methods for detection of these compounds are important for success of experimental visualization of enzymatic reactions in the mixture of proteins by the proteases included in the detergents. The survey study suggests that the method using a kind of urine test paper impregnated with tetrabromophenol blue is superior to other methods of detection.
