Hemicellulase
Hemicellulase is a hemicellulose-targeting hydrolase that breaks down the binding of glucose and polymers to water molecules present in plant fibers. Hemicellulase specifically degrades hemicellulose (such as xylan and mannan) in plant cell walls by hydrolyzing β-1,4-xylosidic bonds and ester bonds (such as acetyl and ferulic acid ester bonds). Hemicellulase relies on the synergistic action of the glycoside hydrolase (GH) and carbohydrate esterase (CE) families to achieve efficient hydrolysis through acid-base catalysis (such as Glu/Asp residues) and substrate binding pockets. Hemicellulase can be used in the food industry (such as improving bread texture), biofuel production (lignocellulose pretreatment) and paper industry (biobleaching)[1][2][3]. Uses: Scientific research. Category: Signaling pathways. CAS No. 9025-56-3. Pack Sizes: 5 g; 10 g; 25 g. Product ID: HY-P2875.

Hemicellulose
Hemicellulose is a complex polysaccharide found in plant cell walls, playing a crucial role in the structural integrity and flexibility of plant tissues. Unlike cellulose, which is made up of long chains of glucose, hemicellulose consists of a diverse mixture of sugars, including xylose, mannose, galactose, and arabinose, arranged in branched chains. It is a major component of plant cell walls, often found alongside cellulose and lignin. Hemicellulose is soluble in alkaline solutions but not in water, and it can be broken down into simpler sugars by hydrolysis. It is used in various industries, including paper and pulp, as a natural binder and stabilizer, and in the food industry, where it serves as a dietary fiber and texture modifier. Its ability to interact with other polysaccharides and proteins makes it an important factor in the functionality and processing of plant-based materials.
