The Citric Acid Cycle

(to the tune of “When Irish Eyes Are Smiling”)
Copyright © 2013 Kevin Ahern

David Simmons' recording HERE

 (This song uses only the chorus of the original song)


The citric acid cycle

Is a source of energy

It gets electrons moving

While reducing NAD


It starts with citric acid

Turning to aconitate

Which becomes an isocitrate

On the way to glutarate


The loss of one more carbon

Gives succinyl-CoA

And then succinic acid

When the CoA goes away


A further oxidation

Gives one trans fumarate

Which gains a water on the

Next step to make malate


One simple oxidation

Makes O-A-A you see

Which combined with Ac-Co-A

Returns us cyclically
