Question

The most abundant organic compound in the world is:
A. Cellulose
B. Alkaloids
C. Methane
D. Chlorophyll

Answer 1

Hint: It's an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. It's the main substance found in plant cell walls and helps the plant to remain stiff. It's a long chain of linked sugar molecules that gives wood its remarkable strength.

Complete answer:
A type of carbohydrate, cellulose, contains chains of glucose rings. Providing strength and rigidity, cellulose forms the cell walls of plants. Cellulose is the primary constituent of wood, making this organic compound the most abundant one on the surface of the Earth. It is a polysaccharide assembled from glucose monomer units. Cellulose is a long chain of linked sugar molecules that gives wood its remarkable strength. It is the main component of plant cell walls, and the basic building block for many textiles and for paper. The links in the cellulose chain are a type of sugar ß-D-glucose.

Rayon or viscose is one of the most common "manufactured" cellulose fibers, and it can be made from wood pulp. Cellulose can be represented by the difference between acid detergent fiber (ADF) and acid detergent lignin (ADL). Luminescent conjugated oligothiophenes can also be used to detect cellulose using fluorescence microscopy or spectrofluorometric methods.

Henceforth, Cellulose is the most abundant organic compound in the world.
Option A is the right answer.

Note: The main applications of Cellulose fibers are in the textile industry, as chemical fertilizers and as fiber reinforcement composites. In addition to this remember humans cannot digest cellulose, but it is important in the diet as fiber.
