Abstract: Galacturonic acid (I) is detd. by measuring the red color a (max. absorption at 510 mμ) formed by heating a soln. of I in concd. H2SO4. Glucuronic acid gives a similar reaction but arabinose (II) and galactose (III) do not. I can be detd. in the presence of ≤30% as much II and ≤10% as much III.
