title: [Determination of the content and degree of esterification of uronic acids in plant tissues and products of their processing].
abstract: A method for quantitative determination of uronic acids and the degree of esterification of their carboxyl groups in plant tissues and products of their processing is described. The method involves determination of the difference between the concentrations of Cu2+ in solution before and after interaction of copper with the substance in question. Copper was determined spectrophotometrically in the form of copper-ammonium complex.
