How many material are present celulose hemicelulose and lignin?
Answers
⛰A straight-chain, insoluble polysaccharide that is composed of glucose molecules linked by beta-1, 4 glycosidic (see GLYCOSIDE) bonds. It is the principal structural material of plants, and as such is the most abundant organic compound in the world. It has also been found in certain sea squirts.
⛰In contrast to cellulose, which is a homopolymer of glucose linked with only β-1,4-glycosidic bonds, hemicellulose contains multiple types of sugar units with variety of glycosidic bonds in one molecule. Therefore, hemicellulose is present in amorphous form. Moreover, the composition depends on plant species and parts.
⛰Lignin is one of the two major components of lignocellulose after cellulose. ... Native lignin, defined here as lignin in its original form present in lignocellulose, is an amorphous polymer made from aromatic building blocks that is different in chemical structure and function from the carbohydrate.
