• enzymology
  • In enzymology, a polysaccharide O-methyltransferase (EC 2.1.1.18) is an enzyme that catalyzes the chemical reaction S-adenosyl-L-methionine + 1,4-alpha-D-glucooligosaccharide ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + oligosaccharide containing 6-methyl-D-glucose units Thus, the two substrates of this enzyme are S-adenosyl methionine and 1,4-alpha-D-glucooligosaccharide, whereas its two products are S-adenosylhomocysteine and oligosaccharide containing 6-methyl-D-glucose units.

  • Ficoll is produced by the polymerization of sucrose molecules with epichlorohydrin to give a polysaccharide with the average molecules weight of 400,000. (sigmaaldrich.com)
  • Polysaccharides are one of four classes of carbohydrates , which in turn are biological molecules that contain primarily carbon (C) atoms flanked by hydrogen (H) atoms and hydroxyl (OH) groups (H-C-OH). (newworldencyclopedia.org)
  • chains
  • Previously, we have synthesized several antitumor polysaccharides having D-glucopyranose, D-mannopyranose, D-ara-binofuranose, or its oligomer, as side chains of (1→3)-β-glucan, or (1→4)-β-glucan by the orthoester method as models of natural antitumor polysaccharides, such as lentinan, etc. (springer.com)
  • In this report, water soluble, branched polysaccharides having L-arabinofuranose or its oligomer, L-arabinopyranose, or D-galactopyranose as side chains were synthesized, and their structures and antitumor activities were determined, in order to investigate the effect of the kind of side chains on the antitumor activity.

  • Polysaccharides are even larger chains of monosaccarides. (newworldencyclopedia.org)
  • made
  • Ginseng polysaccharides are made up of the galacturonic acid, galactose, rhamnose, acidic heteropolysaccharide (which is composed of arabinose), and dextran. (eceurope.com)
  • provide
  • Unrefined grains, starchy and nonstarchy vegetables, legumes and fruit provide various nondigestible polysaccharides called fiber, which fall into two main categories. (livestrong.com)
