Cellulose crystallinity index: measurement techniques and .

May 24, 2010· Cellulose crystallites are thought to be imperfect, and thus a significant portion of the cellulose structure is less ordered; this portion is often referred to as amorphous. A parameter termed the crystallinity index (CI) has been used to describe the relative amount of crystalline material in cellulose.

Difference Between Cellulose and Hemicellulose .

Dec 26, 2016· Cellulose: Cellulose has a strong, crystalline structure and it is resistant to hydrolysis. In contrast to hemicellulose, this has a high molecular weight. Cellulose acts as the supporting material in the plant cell walls. Hemicellulose: Hemicellulose has a random, amorphous structure with little strength. It can be easily hydrolyzed by dilute acid or base and as well as by myriad hemicellulose enzymes.

Dextrin | C18H32O16 - PubChem

Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch.Dextrins are mixtures of linear α-(1, 4)-linked D-glucose polymers starting with an α-(1, 6) bond. Because branched amylopectin and glycogen also contain α-(1, 6) bonds, which α-amylase cannot hydrolyze in humans, the digest resulting from this action contains a mixture of dextrins.
