Abstract
The change of viscosity with time in the system groundnut protein‐caustic soda‐water has been studied over a limited range of concentrations. The concentrations selected were those which gave viscous solutions without gelation. The viscosity was plotted continuously against time for each concentration for 15 hours at 20°. The results are presented in graphical form and are in accord with the hypothesis that globulins have spheroidal or coiled molecules which unwind or unfold to long chains on reaction with caustic soda, and if the reaction proceeds far enough, break down to smaller molecules.

The factors determining the longitudinal relaxation time (Tl) of water protons in protein solutions were investigated by analyzing the effects of thermal denaturation on the Tl of the water protons. We treated the water protons and the protein protons "on a protein surface" as a dipole-dipole couple
