INTRODUCTION.
The change of a soluble sucrase preparation from bananas into an
insoluble preparation was described in a previous paper. I This
change was found to occur on dialysis against running tap water.
The insoluble form showed many of the characteristics of a gel. In
this paper, a more complete study of the factors influencing the formation
of this gel will be presented together with some of its properties
but without considering its possible connection with enzyme activity.
