Fiber glycosidic bonds
WebGlycosidic bonds (also called glycosidic linkages) can be of the alpha or the beta type. Disaccharides: Sucrose is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond. In the process, a water molecule is lost. WebIn the inulin molecules D-fructofuranosyl β-(1→2) linkages are the main glycosidic bonds (Roberfroid, 2000). Lower case n refers to the number of fructose residues in the inulin …

WebThe alpha bonds of carbohydrates are broken down during digestion by specific enzymes. Lactose contains a beta bond, which is digestible by lactase. Most carbohydrates that contain beta-glycosidic bonds are not digestible because humans lack the enzyme needed to break down the bond. A glycosidic bond or glycosidic linkage is a type of ether bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate. A glycosidic bond is formed between the hemiacetal or hemiketal group of a saccharide (or a molecule derived from a … See more Glycosidic bonds of the form discussed above are known as O-glycosidic bonds, in reference to the glycosidic oxygen that links the glycoside to the aglycone or reducing end sugar. In analogy, one also considers S … See more Nüchter et al. (2001) have shown a new approach to Fischer glycosidation. Employing a microwave oven equipped with refluxing apparatus in a rotor reactor with pressure bombs, Nüchter et al. (2001) were able to achieve 100% yield of α- and β-D-glucosides. … See more Before monosaccharide units are incorporated into glycoproteins, polysaccharides, or lipids in living organisms, they are typically first "activated" by being … See more Multiple chemical approaches exist to encourage selectivity of α- and β-glycosidic bonds. The highly substrate specific nature of … See more When an anomeric center is involved in a glycosidic bond (as is common in nature) then one can distinguish between α- and β-glycosidic bonds by the relative stereochemistry of the anomeric position and the stereocenter furthest from C1 in the saccharide. See more Glycoside hydrolases (or glycosidases), are enzymes that break glycosidic bonds. Glycoside hydrolases typically can act either on α- or on β-glycosidic bonds, but not on both. This specificity allows researchers to obtain glycosides in high epimeric excess, … See more Different biocatalytic approaches have been developed toward the synthesis of glycosides in the past decades, which using “glycosyltransferases” and “glycoside hydrolases” are among the most common catalysis. The former often needs expensive … See more
