Hemicellulase vs. Hemicellulose

Hemicellulasenoun

(enzyme) Any enzyme that catalyzes the hydrolysis of hemicellulose

Hemicellulosenoun

(carbohydrate) A mixture of several plant polysaccharides, of smaller molecular weight than cellulose, that are soluble in dilute alkali; they are involved in the manufacture of paper, and are used in the production of furfural and ethanol.

Hemicellulose

A hemicellulose (also known as polyose) is one of a number of heteropolymer (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all terrestrial plant cell walls. While cellulose is crystalline, strong, and resistant to hydrolysis, hemicelluloses have random, amorphous structure with little strength.
