Chemical Properties
Hemicellulose is the least utilized component of the biomass triad comprising cellulose, lignin, and hemicellulose. The term was originated by Schulze (1) and is used here to distinguish the noncellulosic polysaccharides of plant cell walls from those that are not part of the wall structure. Confusion arises because other hemicellulose definitions based on solvent extraction are often used in the literature. The term polyose is used in Europe to describe these noncellulosic polysaccharides from wood, whereas hemicellulose is used to describe the alkaline extracts from commercial pulps.Occurrence
Pure hemicellulose components are seldom extracted directly from their source. Extracts are a mixture of polysaccharides, lignin, and lignin—hemicellulose complexes (by chemical linkages and possibly physical interactions) characteristic of their origin and the solvent employed. Hemicellulose has a lower degree of polymerization (DP) than cellulose (about 200 vs more than 10,000) and its lower limits have not been clearly defined. The extract may contain two or more polymers of similar composition but different structures (polydiversity) or of different distributions and amounts of branching or bonding in otherwise similar molecules (polydispersity). If a single polymer is present, it may exhibit a spectrum of molecular weights (polymolecularity) which may exhibit a Gaussian or biased distribution. A pure hemicellulose component is one where polydiversity has been avoided and a degree of heterogeneity has been attained compatible with end use application.Uses
Hemicellulase can be used in biological study of method for fractionation of biomass devoltalization products.Check Digit Verification of cas no
The CAS Registry Mumber 9034-32-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 9034-32:
(6*9)+(5*0)+(4*3)+(3*4)+(2*3)+(1*2)=86
86 % 10 = 6
So 9034-32-6 is a valid CAS Registry Number.
