Butyrylcholinesterase (BChE), also known as pseudocholinesterase, is an enzyme that is primarily found in the liver and plasma. It plays a crucial role in the hydrolysis of esters, including the breakdown of certain drugs and toxins. Unlike its counterpart, acetylcholinesterase (AChE), which is predominantly located at neuromuscular junctions, BChE is more broadly distributed throughout the body.
