Abstract

Dissociation of tyrosine was studied in aqueous solutions of methanol, ethanol, 1-propanol, and 2-propanol of various concentrations, when the permittivity of all solutions had the same value. The effect of electrostatic interactions was, consequently, equal and thus the other interactions became more pronounced. On the basis of p<i>K </i>values of tyrosine -OH groups these alcohols can be divided into two groups, the first one including methanol and ethanol, the second one both propanols. The observed differences can be explained only qualitatively as a result of interaction of alcohols with tyrosine and with the surrounding water.
