What is Cyclooxygenase?

Cyclooxygenase (COX) is an enzyme that plays a crucial role in the body. It helps produce prostaglandins, which are compounds involved in inflammation and pain. Let's dive into some fascinating facts about this enzyme.

Cyclooxygenase exists in two main forms: COX-1 and COX-2. COX-1 is found in most tissues and helps maintain normal cellular functions. COX-2 is usually induced during inflammation.
COX-1 is often called the "housekeeping" enzyme. It regulates normal cellular processes like protecting the stomach lining and maintaining kidney function.
COX-2 is primarily involved in inflammation and pain. It gets activated in response to inflammatory stimuli, leading to the production of prostaglandins that cause pain and swelling.
Nonsteroidal anti-inflammatory drugs (NSAIDs) target COX enzymes. Medications like ibuprofen and aspirin inhibit COX activity, reducing inflammation and pain.
Aspirin irreversibly inhibits COX-1 and COX-2. This means it permanently deactivates the enzyme, which is why its effects last longer compared to other NSAIDs.
