Cellulose is a type of carbohydrate. Thus option D is correct.
What is cellulose ?
Cellulose is a complex unbranched kind of glucose, a residue polymer formed via beta-1,4 glycosidic connections. It has a chemical formula (C6H10O5)n.
This chiral organic compound is tasteless, odor less, water-soluble and biodegradable.
There are huge application of cellulose in different sectors like paper, textiles, pharmaceuticals, and insulation.
The major classification are monosaccharides which can not be hydrolyzed into simple polyhydroxy aldehydes or ketone units for example glucose, fructose etc.
Oligosaccharides release 2 to 10 monosaccharide units after hydrolysis like Sucrose, maltose.
Polysaccharides are joined by a large number of monosaccharides by glycosidic bond such as starch, cellulose, glycogen.
Three types of major polysaccharides are starch main storage of plants, a polymer of alpha- Glucose and have amylose and amylopectin.
Glycogen are the main storage in animal body and their structure is similar to amylopectin.
Thus option D is correct.
