Aqueous dissociation constants of bile pigments and sparingly soluble carboxylic acids by 13C NMR in aqueous dimethyl sulfoxide: effects of hydrogen bonding

Journal of Lipid Research, 1997
pKas for the acid dissociation of the carboxyl groups of bilirubin in water have been reported recently to be 8.1-8.4, or higher. These high values were attributed to intramolecular hydrogen bonding.
