How to Say Acetylcholinesterase

Acetylcholinesterase, also known as AChE, is an enzyme that exists within the human body and plays a crucial role in the breakdown of acetylcholine, a neurotransmitter responsible for muscle contraction and various other neurological functions. Pronouncing scientific terms can often be challenging, but with a little guidance, you’ll soon be able to confidently say “acetylcholinesterase” in both formal and informal contexts. In this guide, we’ll explore the correct pronunciation of this term, as well as provide you with tips, examples, and variations.
