Breaking it into chunks helps: say "pyruvate" first, then "dehydrogenase," then "deficiency" separately, and it becomes easier to say the whole thing together.
What is the stressed syllable in 'pyruvate'?

What does 'dehydrogenase' mean, and where does it come from?
+
The word comes from Greek and Latin parts: "de-" means to remove, "hydro-" means water, and "-genase" refers to an enzyme. So "dehydrogenase" is an enzyme that removes water and hydrogen atoms from molecules. You'll see this same ending "-genase" in many other enzyme names.
