(To the tune of “Jean”)
Heme, heme, colored supreme
Deepest red I’ve ever seen
When my oxygen’s low
Hemoglobin will know
Give up oxygen, heme
Heme, heme porphyrin ring
Bonded to five histidines
When an oxygen binds
To your iron it climbs
Tugging histidine, heme
Then the globin arranges itself a new way
And the three other units tell their hemes OK
They can go on a bindin’ – oh-two they’re findin’
Then heme, heme leaving the lungs
Travels inside the bloodstream
When it finds a tissue
That is lacking oh-two
It gives what it needs, bloody heme
Heme, you keep me alive
Binding coop’ratively
Go release what I need
Christian Bohr has decreed
Tissues adore you, lovely heme
