✦ Synopsis

A physlcochemlcal model membrane v, Lth characteristics that mimic glucose and galactose transport in the intact er~throcyte has been reported prewously The model reqmred erythrocyte hpJd for th~s behavtor lntroduchon of pure cholesterol instead of er~throcyte lipid into the model results m virtually ldent,cal transport rates for D-glucose and D-galactose Both the 'nonacldlc" and ' acidic' chromatographic frachons of erythTocyte phosphohpld, accelerate the transport of D-galactose relative to D-glucose at 1 3 M concentratlon Each commercial phosphohp,d tested, (lecithin, phosphahdyl ethanolamme. sphmgomyehn, phosphahdyl serme, and phosphahdyl mos,tol), has the same effect The reason for thl~ achon of the phosphohplds IS at present unkno~n
