Phospholipase A

Phospholipase A is an enzyme that plays a key role in breaking down cell membranes, specifically targeting phospholipids, which are molecules that form the membrane's bilayer. It cleaves fatty acid chains from these phospholipids, releasing substances like arachidonic acid that can be used to produce signaling molecules involved in inflammation and other processes. This enzyme is important in biological functions such as cell signaling, immune response, and inflammation regulation. Its activity must be carefully controlled, as excessive or inappropriate action can contribute to inflammatory diseases.
