Acetylcholinesterase is widely used in medical and agricultural fields. In medicine, it plays a crucial role in diagnosing and treating conditions like Alzheimer's disease, where its inhibitors help improve cognitive function. It is also used in managing glaucoma and myasthenia gravis by enhancing nerve signal transmission. In agriculture, acetylcholinesterase inhibitors are key components of pesticides, effectively controlling insect populations by disrupting their nervous systems. Additionally, it is utilized in research to study neurobiology and develop new therapeutic agents targeting neurological disorders.
