Prostaglandins are a group of lipid compounds that are produced in the body and have various important functions. They are derived from fatty acids and play a key role in processes such as inflammation, blood flow, and the formation of blood clots. Prostaglandins act as signaling molecules, helping to regulate many physiological functions. These compounds are involved in the body's response to injury and illness, often promoting pain and fever as part of the healing process. They are also important in reproductive health, influencing processes like menstruation and labor. Due to their diverse roles, prostaglandins are a target for certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs).
