摘要

We investigated the effect of conjugation with the aromatic amino acid tyrosine on the critical micellar concentration (CMC) of bile salts. The CMC values were determined by surface tension and by dye solubilization. The surface tension measurement employed the Du Nouy ring detachment method and the dye solubilization measurement utilized a water-insoluble dye, 1-O-tolylazo-2-naphthol. We compared the CMC values of the sodium salts of cholyltyrosine (cholylTyr), deoxycholyltyrosine (deoxycholylTyr), deoxycholylglycyltyrosine (deoxycholylGlyTyr) chenodeoxycholyltyrosine (chenodeoxycholylTyr), chenodeoxycholylglycyltyrosine (chenodeoxycholylGlyTyr), cholyldiglycyltyrosine (cholylGlyGlyTyr) and cholylglycyltyrosine (cholylGlyTyr) with their respective glycine conjugated bile salts. Both techniques of CMC determination indicated that tyrosine conjugation to free and glycine-conjugated bile salts reduced their CMC significantly.
