It can be broken down chemically into its glucose units by treating it with concentrated mineral acids at high temperature.
Cellulose is derived from D-glucose units, which condense through β(1→4)-glycosidic bonds.
What does acid hydrolysis do to cellulose?
When cellulose is hydrolyzed in an acidic medium to glucose, the P-l,4-glucosidic bonds of a cellulose chain molecule are split by the addition of water molecules; this addition yields fragments of shorter chain lengths while preserving the basic structure.
What is acid hydrolysis of glucose?
Dilute acid hydrolysis is a process in which cellulose is hydrolyzed to glucose monosaccharide by using an inorganic acid such as sulfuric acid or hydrochloric acid as the catalyst, generally under a 10% (w/w) load.
What happens when cellulose is hydrolyzed to glucose?
Abstract.
As the main component of lignocelluloses, cellulose is a biopolymer consisting of many glucose units connected through β-1,4-glycosidic bonds.
Breakage of the β-1,4-glycosidic bonds by acids leads to the hydrolysis of cellulose polymers , resulting in the sugar molecule glucose or oligosaccharides .
