Common Mispronunciations of Acetylcholine
Not uh-se-tuhl-CHOH-leen
The ch in choline is a hard k, as it is throughout the Greek chemical vocabulary: chlorine, cholesterol, chromosome.
Not AY-suh-tyl-koh-leen
The first two parts are both light and quick, and the beat waits for KOH. A strong opening also lengthens the a, which stays short here.
Tip: Split it into its two halves: acetyl, which is uh-SE-tuhl, then choline, KOH-leen, and let the second half take the main beat.
