Verified step by step guidance
1
Understand the structure and function of chitin: Chitin is a long-chain polymer of N-acetylglucosamine, a derivative of glucose. It is primarily found in the cell walls of fungi, as well as in the exoskeletons of arthropods.
Identify the organisms that contain chitin: Among the options provided, fungi are the only organisms that have chitin in their cell walls. Viruses, protozoa, and bacteria do not contain chitin.
Consider the mechanism of the drug: If a drug targets chitin, it is likely designed to disrupt the structural integrity of the cell wall in organisms that contain chitin, leading to their destruction or inhibition.
Evaluate the effectiveness of the drug: Since fungi have chitin in their cell walls, a drug targeting chitin would be effective against fungal pathogens.
Conclude the application of the drug: Based on the presence of chitin, the drug should be effective against fungi, as they are the only type of pathogen listed that contains chitin.
