glycosidic bondhydroxylDFTAIMDMechanistic 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...
Alpha Helix and Beta Sheet The primary structure of a protein is the amino acid sequence of the polypeptide chain. The way the polypeptide chain forms hydrogen bonds determines the secondary structure. There are two main types of secondary structures in proteins, alpha helices and beta pleated ...
While 45 displays excellent potency in vitro its further development has not been pursued due to other liabilities, namely that it is quantitatively converted by adenosine deaminase to inosine as well as having slower glycosidic bond cleavage to adenine by purine nucleoside phosphorylase.174 A further...
(1978) Primary structural requirements for the enzymatic formation of the N-glycosidic bond in glycoproteins. J. Biol. Chem., 254, 9747-9753.Hart, GW, Brew, K, Grant, GA, Bradshaw, RA, Lennarz, WJ (1978) Primary structural requirements for the enzymatic formation of the N-glycosidic bond...
were detected mainly based on the characteristic fragment ions originating from quinovosidic bond cleavages in their molecules. Following an LC-MS-guided separation technique, seven new aminooligosaccharides (10–16) along with four known related compounds (17–20) were obtained directly from the cru...
achieve the purpose of degradation, which is more rapid and low-cost [17]. In the acid degradation method, some inorganic acids, such as phosphoric acid and hydrochloric acid, are adopted to cause the glyosidic bond breakage, which degrade the polysaccharide into low molecular substances, and ...
