Structural analysis of the non-dialysable urinary glucoconjugates of normal men

Abstract

Enzymic methods were employed to analyse the structure of the non-dialysable urinary glucoconjugates of ten healthy males. The excretion of the urinary glucoconjugates was determined from the glucosyl: galactosyl ratio after acid hydrolysis, and a mean value of 0.27 was obtained. The results of the specific actions of α-and β-glucosidases showed that the non-dialysable urinary glucoconjugates contain a branched α-glucan fraction with 1,4- and 1,6-glucosidic bonds, and a β-glucan fraction containing 1,4-glucosidic bonds.
