demonstration of acid hydrolysis of polysaccharides

How does acid hydrolysis affect polysaccharides?
Moreover, apart from the cleavage of the glycosidic bond in polysaccharides, acid hydrolysis may lead to excessive degradation of released monosaccharides under harsh condition or long treatment time ( Whitfield et al., 2016 ). In this instance, some sugars may degrade to non-sugars that may deepen the color of reaction solutions.
How are polysaccharides broken down?
Polysaccharides, such as starch, chitin, glycogen, and cellulose, can be broken down into monosaccharides. This occurs through the process of hydrolysis, which uses water to break the bonds between monosaccharides. Want to join the conversation?
What is a two-step hydrolysis method for polysaccharide composition analysis?
Two-step hydrolysis method for monosaccharide composition analysis of natural polysaccharides rich in uronic acids Methylation analysis of polysaccharides: technical advice A robust and universal NMR method for the compositional analysis of polysaccharides
How enzymatic hydrolysis is used to determine monosaccharide composition?
As a gentle and specific method, enzymatic hydrolysis for determining monosaccharide composition of polysaccharides depends on enzyme catalyzing the cleavage of selected glycosidic bonds ( Guan & Li, 2010; Li et al., 2016; Ma et al., 2018 ). By using the enzymatic method, the undesirable destruction of liberated monosaccharides will not occur.
