nonreducing การใช้

• The catabolic process occurs at the nonreducing end of glycogen.
• Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing.
• These enzymes exhibit strict acceptor specificity, recognizing nonreducing terminal sugars and their anomeric linkages.
• Since it contains no anomeric hydroxyl groups, it is classified as a nonreducing sugar.
• In the hIgG-hGH conjugate Western blot ( nonreducing conditions ), two separate bands with different molecular weights are visible after immunodetection.
• When glycogen is broken down to be used as an energy source, glucose units are removed one at a time from the nonreducing ends by enzymes.
• An example of this is glycogen breakdown by glycogen phosphorylase, which catalyzes attack by inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule.
• However, sucrose and trehalose, in which the anomeric carbons of the two units are linked together, are nonreducing disaccharides since neither of the rings is capable of opening.
• HEXB is one of the two subunits forming ?-hexosaminidase which functions as a glycosyl hydrolase that remove ?-linked nonreducing-terminal GalNAc or GlcNAc residues in the lysosome.
• It binds specifically to certain structures found in various sugars, glycoproteins, and glycolipids, mainly internal and nonreducing terminal ?-D-mannosyl and ?-D-glucosyl groups.
• It is a reducing sugar with only one reducing end; no matter how large the glycogen molecule is or how many branches it has, each branch ends in a nonreducing sugar residue.
• Nonreducing disaccharides like sucrose and trehalose have glycosidic bonds between their anomeric carbons and thus cannot convert to an open-chain form with an aldehyde group; they are stuck in the cyclic form.
• The glycogen branching enzyme catalyzes the transfer of a terminal fragment of six or seven glucose residues from a nonreducing end to the C-6 hydroxyl group of a glucose residue deeper into the interior of the glycogen molecule.
• Normally they can be found as components of oligosaccharide chains of mucins, glycoproteins and glycolipids occupying terminal, nonreducing positions of complex carbohydrates on both external and internal membrane areas where they are very exposed and develop important functions.
• What is notable about sucrose is that unlike most disaccharides, the glycosidic bond is formed between the reducing ends of both glucose and fructose, and not between the reducing end of one and the nonreducing end of the other.
• "' Melezitose "', also spelled "'melicitose "', is a nonreducing trisaccharide sugar that is produced by many plant sap eating insects, including aphids such as " Cinara pilicornis " by an enzyme reaction.
