Experimental and Calculated Amino Acid Composition of Micellar Calcium Phosphate ... 

Caseins are the principal group of proteins in milk. They are present in three different forms (a, 8, k), whose amino acid composition and sequence have been determined (1). These proteins show a micellar organization, which form a colloidal dispersion in milk. 

The amino acid and ionic composition of micellar calcium phosphate can be used to estimate the degree of protonation of the phosphate groups. By summing the positive and negative charges, a charge... 

Capillary zone electrophoresis (CZE), micellar capillary electrokinetic chromatography (MECC), capillary gel electrophoresis (CGE), and affinity capillary electrophoresis (ACE) are CE modes using continuous electrolyte solution systems. In CZE, the velocity of migration is proportional to the electrophoretic mobilities of the analytes, which depends on their effective charge-to-hydrodynamic radius ratios. CZE appears to be the simplest and, probably, the most commonly employed mode of CE for the separation of amino acids, peptides, and proteins. Nevertheless, the molecular complexity of peptides and proteins and the multifunctional character of amino acids require particular attention in selecting the capillary tube and the composition of the electrolyte solution employed for the separations of these analytes by CZE.
