Metabolism of D-glucuronic acid and D-galacturonic acid by Phaseolus aureus seedlings.
n-Glucuronic acid and its la&one are known to be converted to polysaccharides by plant tissues. Ripening strawberries have been shown to incorporate the intact carbon skeleton of D-ghcuronolactone into pectin (1). It has also been demonstrated that wheat plants and corn coleoptiles incorporate n-glucuronic acid and its lactone into the pentosyl moieties of pentosan with loss of carbon 6 (2,3). ...
متن کاملDerivatives of Glucuronic Acid
The presence of glucuronic acid in the complex molecules of specific bacterial polysaccharides (1) has stimulated a study of certain derivatives of this important substance and its lactone, glucuron. These investigations have entailed the necessity of elaborating a satisfactory method for preparing both the acid and its lactone, and at the same time they have embraced a study of the comparative...
متن کاملGlutathione stabilizes ascorbic acid in aqueous solution
This report shows that glutathione affects ascorbic acid degradation in aqueous solution resulting in a significant stabilization of the vitamin. For the GSH concentrations used in this work the effect was higher on diluted ascorbic acid solutions. It is also shown that for a fixed ascorbic acid concentration, as glutathione concentration increases the degradation reaction shifts from first to ...
متن کاملThe Production of Glucuronic Acid in Scurvy
In a recent publication Rygh and Rygh (1) reported that guinea pigs kept on a scurvy-producing diet lost their ability to synthesize glucuronic acid; and furthermore, that, if methylnornarcotine and glucuronic acid were added to a vitamin C-free diet, the development of scurvy was prevented, The possible significance of these results is obvious. The methods, however, employed by these authors f...
متن کاملDissociation constants of D-galacturonic and D-glucuronic acid and their О-methyl derivatives
Dissociation constants (pK, 20°C) of D-galacturonic acid, D-glucuronic acid, their O-methyl derivatives, as well as of the corresponding 4,5-unsaturated substance have been determined by means of discontinuous Potentiometrie titration. The found pK values have been interpreted from the point of view of inductive and mesomeric effects, and nonbonding interactions. It is demonstrated that the eff...
