Propionic acid (PA) is a short chain fatty acid, a common food preservative and metabolic end product of enteric bacteria in the gut. The present study was undertaken to investigate the effect of PA on liver injury in male rats. Male western albino rats were divided into two groups. The first group served as normal control, the second was treated with PA. The activities of serum hepatospecific ...

Article info: Received: 18 October 2012 Accepted: 10 December 2012 ABSTRACT Orange and lemon peels were used for obtaining pectic polysaccharides. Citrus peels were previously treated with 96% ethanol, and the obtained alcoholinsoluble solids (AIS) were subjected to a sequential extraction with hot distilled water and hot 0.5% HCl. Waterand acid-extracted orange (WEOP and AEOP) and lemon (WELP ...

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...
