Mechanistic insights into glycosidic bond activation in cellulose pyrolysis were obtained via first-principles density functional theory calculations that explain the peculiar similarity in kinetics for different stereochemical glycosidic bonds (beta vs alpha) and establish the role of the three-dimensional ...
A cytosolic enzyme (EC 3.2.1.21, 469aa) that catalyses the release of glucose by hydrolysis of the glycosidic link in various β-D-glucosides (compounds of the form R-β-D-glucose, where the group R may be alkyl, aryl, mono- or oligosaccharide). Favoured source: almonds, from which en...
glycosidic linkage with Tyr should beα-linked, we introduced an azido group to replace the Troc moiety and thereby facilitated the formation of theα-glycosyl linkage. The Troc moiety was cleaved with zinc and acetic acid with subsequent removal of the Ac protecting groups (to prevent Ac migrat...
A ribonucleotide unit comprises an hydroxyl group attached to the 2′ position of a ribosyl moiety that has a nitrogenous base attached in N-glycosidic linkage at the 1′ position of a ribosyl moiety, and a moiety that either allows for linkage to another nucleotide or precludes linkage. siRNA...
The present invention relates to use of an enzyme that cleaves both alpha- and beta-1,4-glycosidic bonds and, more particularly, the present invention provides α-L-fucosidase which has α-1,4-glucosidase and β-1,4-galactosidase activities and thus is capable of producing glucose and/or ...

(1,6)-glycosidic bonds possessing insoluble properties. From the meta-analysis, the weight gain and feed intake of nursery pigs increased by 7.6% and 5.3%, respectively, through the use of yeast β-glucans (fromSaccharomyces cerevisiae), and increased by 11.6% and 6.9%, respectively, through ...
Chitosan is a polysaccharide composed of N-acetyl-D-glucosamine and D-glucosamine units linked by 1-4-β-glycosidic bonds. Its structure provides −NH2 groups that are protonated at low pH [40], favoring interaction with the negatively charged stratum corneum [41]. In addition, chitosan has ...
