What are some examples of enzyme inhibitors?

Enzyme inhibitors are substances that slow down or stop enzyme activity. Some examples include competitive inhibitors like statins, which inhibit HMG-CoA reductase, and non-competitive inhibitors like aspirin, which inhibits cyclooxygenase.

How do competitive and non-competitive inhibitors differ?

Competitive inhibitors bind to the active site of the enzyme, competing with the substrate. Non-competitive inhibitors bind to a different site, changing the enzyme's shape and reducing its activity regardless of substrate presence.

Can you give me a specific example of a drug that acts as an enzyme inhibitor?

Sure! One specific example is ibuprofen, which acts as a non-competitive inhibitor of cyclooxygenase enzymes, reducing pain and inflammation.

Are there any natural enzyme inhibitors?

Yes, there are natural enzyme inhibitors. For example, certain compounds in garlic can inhibit the enzyme ACE, which helps regulate blood pressure.
