pectic การใช้

• The increase in serum viscosity is due to the extraction of pectic substances into the serum.
• The free carboxyl groups interact with cations to form insoluble pectic acid divalent metal ion complexes.
• The project resulted in four papers on pectic enzymes, one of which published in Nature.
• This is facilitated by the addition of pectolytic enzymes which are long chain carbons composed of pectic compounds.
• RR is a stereoselective stain for pectic acid, insofar as the staining site occurs between each monomer unit and the next adjacent neighbor.
• Homogalacturonan is highly methyl-esterified when exported into cell walls and is subsequently de-esterified by the action of pectinesterase and other pectic enzymes.
• L-Rhamnose is abundant in biomass as a common constituent of glycolipids and glycosides, such as plant pigments, pectic polysaccharides, gums or biosurfactants.
• Pectinesterase catalyses the de-esterification of methyl-esterified D-galactosiduronic acid units in pectic compounds yielding substrates for depolymerising enzymes, particularly acidic pectins and methanol.
• His master's research topic was the spoilage and softening of pickles during fermentation, a phenomenon that, he concluded, was probably caused by pectic enzymes.
• The salts of partially esterified pectins are called pectinates, if the degree of esterification is below 5 percent the salts are called pectates, the insoluble acid form, pectic acid.
• Demain said that he and Phaff  apparently were the first in the world to carry out affinity chromatography, using a pectic acid gel to selectively adsorb YPG from culture filtrates.
• "' Pectic acid "', also known as "'polygalacturonic acid "', is a water-soluble, transparent gelatinous acid existing in ripe fruit and some vegetables.
• While the cell walls will generally not burst, the de-polymerization of the pectic polysaccharides that connect the vegetable cells together and / or the gelatinisation of starch in the vegetable can be achieved without overcooking.
• Pectic compounds are complex heteropolysaccharides in that their chemical composition includes a chain structure of axial-axial ?-1.4-linked d-galacturonic acid unit along with blocks of L-rhamnose regions that have side chains of arabinose, galactose, and xylose.
• When " D . dadantii " is virulent it enters primarily through hydathodes and wounds, with the assistance of jasmonates, where the bacteria rapidly breakdown the parenchymatous tissues with the use of pectic enzymes ) . " D . dadantii " produces many pectinases that are responsible for disassembly of the plant cell wall.
• Spending  four years under the tutelage of the prominent yeast scholar, Herman J . Phaff,  who became his second mentor, Demain  elucidated the mechanism of pectic acid degradation by the extracellular polygalacturonase ( YPG ) of the yeast Klyveromyces fragilis,  later recalling that the two men  worked from early morning until evening, went home for dinner with our spouses, and returned to the lab for research and discussions that lasted until the wee hours .
