Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, cellulose, and chitin, are widely found in plants, animals, and microorganisms.
The mechanical stress is capable of breaking the glycosidic bonds of the fibrous matrix, increasing the soluble fiber content, often used as a prebiotic (VITAGLIONE et al., 2008).
Cellulolytic enzymes degrade cellulose by cleaving the glycosidic bonds. Many fungi and bacteria are capable of producing multiple enzymes, collectively known as cellulases, that act in a synergistic manner to hydrolyze the [beta]-1,4-D-glycosidic bonds within the cellulose molecule (Akiba, Kimura, Yamamoto, & Kumagai, 1995).
Type II pullulanase also known as amylopullulanase hydrolyzes [alpha]-1,6 glycosidic bonds in pullulan and [alpha]-1,6 as well as [alpha]-1,4 glycosidic bonds in starch.
Such fact can be attributed to the presence of D-galactopyranose and D-mannopyranose, respectively, revealing the coexistence of glycosidic bonds [17,18].
Moreover, in most fruits and vegetables, flavonoids contain glycosidic bonds and exist as dimers and oligomers, and the industrial processing such as heating or boiling results in the formation of monomers by the hydrolysis of glycosidic bonds [27].
For the case of employing oligosaccharides as starting sugars, acetal exchanges of the inner glycosidic bonds would take place as a result of intermolecular protonations by the acid catalyst to the glycosidic oxygens (Fig.
The amylases act on [alpha]-1-4 glycosidic bonds and are therefore also called glycoside hydrolases.
Amongst the various substrates, acid swollen chitin was found to be the best substrate for chitinase when used at the concentration of 1% exhibiting its high specificity in catalyzing glycosidic bonds between N-acetylglucosamine residues.
In non-physiological conditions, the hydrolysis constant of glycosidic bonds has been around 50% with high concentrations of amylase enzyme.
is 3.2.1.1) is an extracellular enzyme, which splits a-1, 4- glycosidic bonds of starch and produces glucose, maltose and alpha limit dextrin [1].The substrate of amylase is starch, which is a polysaccharide and composed of two types of polymers amylose and amylopectin.
Glycosides represent a latent pool of aroma compounds, where the aglycone is conjugated to glucose and a second sugar molecule via glycosidic bonds that require either heat or enzymatic activity to release the active aroma compound.
