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.

A large number of bacteria and fungi secrete extracellularly the enzyme complex often termed 'pectinase', which causes the rapid disintegration of plant tissue and is consideredtheprimaryinstrument of the attack on plant tissues by these microorganisms. The action of pectinase on a solution of pectin results in the following changes: (a) a rapid lowering of the viscosity of the solution; (b) a ...

Acertain number of plant exteracts are known to stimulate milksecretion in lactaiting women .These extracts injected intravenously to Eweor administered orally induced a marked secretion of Prolactin. Thecompound which proved to be active in the plant exteracts wasPectin.Pectic acid which stimulates Prolactin release in vivo were added.Tothe culture mediumof the GH3/B6 rat p...

Arabinans and galactans are neutral pectic side chains and an important part of the cell walls of dicotyledonous plants. To get a detailed insight into their fine structure, various oligosaccharides were isolated from quinoa, potato galactan, and sugar beet pulp after enzymatic treatment. LC-MS(2) and one- and two-dimensional NMR spectroscopy were used for unambiguous structural characterizatio...

the genus fusarium is a species rich genus. different media are required to study themorphological characters and classify different species, a time consuming technique. in this study pecticzymograms were used to identify species and form species of fusarium isolates. fusarium isolates (318) wereobtained from different areas and hosts in isfahan province, iran. isolates were identified to speci...

Yeast polygalacturonase catalyzes a random hydrolysis of pectic acid to a mixture of digalacturonic and galacturonic acids via a series of oligogalacturonides (1). This enzyme will be termed yeast endo-polygalacturonase to differentiate it from end group-hydrolyzing enzymes, which have been named exopolygalacturonases (2). Evidence has been presented that yeast endo-polygalacturonase is a singl...
