What process breaks down cellulose?
Cellulolysis is the process of breaking down cellulose into smaller polysaccharides called cellodextrins or completely into glucose units; this is a hydrolysis reaction.
Because cellulose molecules bind strongly to each other, cellulolysis is relatively difficult compared to the breakdown of other polysaccharides.
What is the mechanism of cellulase hydrolysis?
Cellulases cleave glucosidic bonds by using acid-based catalysis.
The hydrolysis is performed by two catalytic residues of the enzyme: a general acid (proton donor) and a nucleophile/base.
The catalytic mechanism which occurs depends on the spatial position of the catalytic residues.
Why is cellulose hydrolysis important?
Glucose produced by catalytic hydrolysis of cellulose is an important platform molecule for producing a variety of potential biobased fuels and chemicals.
Catalysts such as mineral acids and enzymes have been intensively studied for cellulose hydrolysis.
Cellulose is a polysaccharide with beta ( 1→4 ) glycosidic linkages which cannot be hydrolyzed easily.
Also, there is no enzyme present in human body to digest it.
Why is cellulose more difficult to digest than other polysaccharides?
