BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms and is said to be the most abundant organic molecule on Earth.

Detailed explanation-2: -The structural polysaccharide found in plant cell walls is cellulose while the storage polysaccharide found in seeds is starch.

Detailed explanation-3: -Chitin is a structural polysaccharide found in the species such as yeast, fungi, insects, and marine invertebrates. Structurally, Chitin is a homopolymer of N-acetyl glucosamine with -(1, 4) linkages, while chitosan is deacetylated chitin.

Detailed explanation-4: -Chitin occurs in the cell wall of fungi and makes up the exoskeleton of arthropods while cellulose occurs in the cell wall of plants and algae.

Detailed explanation-5: -Chitin occurs in the structural components of arthropod exoskeletons or in the cell walls of fungi and yeast [42]. Chitin and cellulose are almost similar polysaccharide compounds; cellulose contains a hydroxyl group, whereas chitin contains an acetamide group.
