Acetylcholine chloride

Acetylcholine chloride (pronounced as a-set-il-KOH-leen KLOR-ide) is a chemical compound used in medicine. It is a type of neurotransmitter, which means it helps to transmit signals in the brain.

Etymology

The term "acetylcholine" is derived from its structure. It is made up of an acetyl group (from acetic acid) and a choline molecule. The "chloride" part of the name refers to the chloride ion that is part of the compound.

Use in Medicine

In medicine, acetylcholine chloride is used to stimulate the Parasympathetic nervous system. It is also used in eye surgery to make the pupil of the eye smaller.
