Acetylcholine: A neurotransmitter released by nerves that is essential for communication between the nerves and muscles.
Acetylcholinesterase: An enzyme that breaks down the neurotransmitter acetylcholine at the synaptic cleft (the space between two nerve cells) so the next nerve impulse can be transmitted across the synaptic gap. Pesticides of the organophosphate and carbamate types act to paralyze and kill insects by inhibiting their acetylcholinesterase. Abbreviated AChE.
Acetylcysteine: An antioxidant drug used to reduce the thickness of mucus and ease its removal. It is also used to reverse the toxicity of high doses of acetaminophen. Acetylcysteine with hydration significantly reduces the risk of contrast nephropathy in patients with chronic renal insufficiency. Also called N-acetyl-L-cysteine.
