Tag: food and it's constituents

Cellulose, Fructose, and maltose are carbohydrates but pepsin is an enzyme made of protein.

Cutin is a polymer of glycerol and certain types of fatty acids. It is an integral part of the cuticle of the leaf. 

Inulin is a storage polysaccharide in roots of Dahlia and related plants. It is also known as a fructan. It is not metabolized in the human body and is readily filtered through the kidney. Therefore, it is used in testing kidney function. Thus, the correct answer is B.

Macro-molecule chitin is a complex nitrogen-containing polysaccharide containing amino sugars and chemically modified sugar for example -glucosamine, N-acetyl-galactosamine etc.

Green plants produce carbohydrates by the process of photosynthesis by using water, carbon die oxide and solar energy. Apart from this, some bacteria and algae can also produce carbohydrates in the form of food. 

Chitin is the substance which is fibrous and made up of the long-chain polymer of N-acetylglucosamine, is a derivative of glucose. It is a major constituent of the exoskeleton of arthropods, crabs and also make the cell wall of fungi.

• Primary metabolites are those that are formed during the growth phase and supports in the overall development of cells. E.g., Carbohydrates, vitamins, proteins etc.
  
• Secondary metabolites are those which are the end products of primary metabolites and are required for ecological activities of cells. E.g., Carotenoids, morphine etc. 

Starch is a type of polysaccharide which is present in rice. Glycogen is stored polysaccharide in animal tissues.

The glycosidic bond is a bond that holds a carbohydrate molecule with another group, which may or may not be a carbohydrate. Polysaccharides contain several monosaccharides that are linked to one another by glycosidic bonds. In water each water molecule binds four other water molecules by hydrogen bonds. This helps the water molecules to hold together (cohesion of water). 

Chitin carbohydrates are the oldest in the given as it is a carbon-based factor. protein, lipids consist chain of nitrogen, hydrogen and carbon atoms however carbohydrate consists of a longer chain of carbon as well as various other groups of compounds. so, the correct option is 'chitin carbohydrates'.
