THE "BOUND" WATER OF BIOLOGICAL COLLOIDS: A REPLY

J Gen Physiol. 1934 Sep 20;18(1):93-6. doi: 10.1085/jgp.18.1.93.

Abstract

The objection by Bull to the estimation of bound water by ultrafiltration, because of an assumed adsorption of the reference substance, has been found invalid for glucose. No adsorption of glucose by the proteins, casein and gelatin, could be detected. The estimation of the bound water of proteins from the probable surface adsorption of water by proteins leads to only a small value.
