The extracellular hemoglobin of the earthworm Lumbricus terrestris has four major kinds of O2-binding chains: a, b, and c (forming a disulfide-linked trimer), and chain d. Non-heme, non-globin structural chains, "linkers," are also present. Light-scattering techniques have been used to show that the ferrous CO-saturated abc trimer and chain d form an (abcd… CONTINUE READING
