Abstract

The interaction of gossypin, congossypin and glycinin with gossypol was studied by the difference spectral technique as a function of pH, ionic strength and temperature. With gossypin, an increase in pH decreased the binding constant to a minimum and then caused an increase. With congossypin the opposite effect was true while with glycinin there was a continuous decrease in binding. Increasing the ionic strength decreased the binding affinity, and increasing the temperature increased the binding affinity with gossypin and congossypin while it decreased with glycinin.
