therefore , the characteristics of ( a ) the uptake of 2-amino [ i-14c ] -isobutyric acid ( aib ) by isolated placental villi , ( b ) gammaglutamyltranspeptidase ( ggtp ) , a critical enzyme of the gammaglutamyl cycle ( ggc ) for the uptake of amino acids in human placenta , and ( c ) lipid structural parameters ( reciprocal of fluidity ) , by steady state fluorescence polarization of plasma membrane vesicles of microvilli ( mv ) and microsomal membranes ( mm ) of umbilical and chorionic plate arteries of placentae of smoking and non-smoking mothers were investigated .
