Four chains, four irons, one job. Three versions of it: the adult molecule, the one residue that turns it into a disease, and the one a fetus makes to take oxygen from its mother.

Read out of each deposition by the baker — nothing on this page types a residue name. Highlighted where this structure differs from the adult one.

Colour is secondary structure (helix, strand, coil), the repo default — hemoglobin is all helix, so the ribbon is nearly one colour and the chains read by shape. Ball-and-stick inside: the hemes with their irons in rust, the two histidines that hold each one, and β6 with the pocket it reaches for.
