THE PREPARATION OF cl-GALACTURONIC ACID FROM LEMON PECTIC ACID.*
A noteworthy advance in the knowledge of the constitution of the pectic compounds was afforded through the excellent researches of Ehrlich and his coworkers (1)) who discovered that d-galacturonic acid, an isomer of d-glucuronic acid, was a constituent of all pectic substances so far examined. Later researches showed that the pectic acid obtainable from sugar beet pectin (2) can be regarded as ...

متن کاملThe pectic disaccharides lepidimoic acid and β-d-xylopyranosyl-(1→3)-d-galacturonic acid occur in cress-seed exudate but lack allelochemical activity.
BACKGROUND AND AIMS Cress-seed (Lepidium sativum) exudate exerts an allelochemical effect, promoting excessive hypocotyl elongation and inhibiting root growth in neighbouring Amaranthus caudatus seedlings. We investigated acidic disaccharides present in cress-seed exudate, testing the proposal that the allelochemical is an oligosaccharin-lepidimoic acid (LMA; 4-deoxy-β-l-threo-hex-4-enopyranuro...
متن کاملPreparation of Alkyl Esters of Pectin and Pectic Acid
Alkyl esters of pectin and pectic acid have been prepared via three different synthetic routes. Enhancements of intrinsic viscosity, binding to bile acids and to isolated soy protein were shown for these novel pectin derivatives. The development of new and improved pectin-containing products may be enhanced by the ease of preparation and improved functionality of such compounds.
متن کاملMetabolism 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). ...
