1925D. R. Nanji et al. in Jrnl. Soc. Chem. Industry 253 t/2 Lactose oxidised by bromine in presence of calcium carbonate yields a dicarboxylic acid from which galacturonic acid can be obtained on hydrolysis, whilst sucrose under similar treatment yields glycuronic acid. We shall refer to these compounds as ‘uronic’ acids. 1946Nature 24 Aug. 271/1 The viscosity of solutions containing the ‘recovered’ sodium alginate is..higher..than that of solutions of salts of low molecular uronic acids. 1982N. B. Schwartz in T. M. Devlin Textbk. Biochem. viii. 430 The long heteropolysaccharide chains are made up largely of disaccharide repeating units, in which one sugar is a hexosamine and the other a uronic acid. |
