To explore the independence of functional group contributions to permeability of nonelectrolytes across egg lecithin bilayers, the transport rates were measured of a series of alpha-substituted p-methylhippuric acids (-H, -Cl, -OCH3, -CN, -OH, -COOH, and -CONH2) across egg lecithin lipid

The barrier domain solubility-diffusion theory of lipid bilayer permeability relates the permeability coefficient (P(m)) to the solute's partition coefficient (PC(barrier/w)) and diffusion coefficient (D(barrier)) in the ordered chain region of the bilayer that serves as the barrier region for polar

The separation of hippuric and m-methylhippuric acid as toluene and m-xylene metabolites present in urine of people exposed simultaneously to toluene and xylene is described. Chloroform was used for hippuric and m-methylhippuric acid extraction. Satisfactory separation of these metabolites was
