Most abundant organic material on earth is
The most abundant organic compound in the terrestrial environment is cellulose. Cellulose is a polymeric polysaccharide consisting of only one type of monosaccharide i.e., glucose. Homopolysaccharides are polysaccharides composed of a single type of sugar monomer. For example, cellulose.
Monosaccharides, also called simple sugars, are the most basic units of carbohydrates.
Disaccharide is the sugar formed when two monosaccharides are joined by glycosidic linkage.
If the polysaccharide molecules are formed by different kinds of monosaccharides, they are known as heteropolysaccharides.
