Question

Which of the following option is not related with the other three options?

• A. Keratin
• B. Elastin
• C. Dextrin
• D. Collagen

Answer 1

The correct option is C Dextrin

Keratin is a family of fibrous structural proteins. It is the protein that protects epithelial cells from damage or stress that has potential to kill the cell.

Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting.

Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch or glycogen.

Collagen is the main structural protein in the extracellular space in the various connective tissues in animals.

As Dextrin is a carbohydrate, whereas rest others are proteins, hence it is unrelated. Hence, option C is correct.
