Hemoglobin Structure and Function in the Rat-Tailed Sea

vascular hemoglobin. The oxygen affinity of water vas-cular hemoglobin was not different from that of the peri-visceral hemoglobin in spite of the difference in structure and location in the animal. The exceptionally high oxygen affinity hemoglobin of P. chilensis, a burrowing sea cu-cumber, may be adaptive to this animal's oxygen-limited habitat.


The atomic structure of myoglobin, an oxygen binding protein, is drawn here as a stick model. The overall conformation of a protein such as myoglobin is a function of its amino acid sequence.

in hemoglobin has a higher affi nity, roughly 200 250 times greater, for CO as compared to oxygen. Given its high affi nity, CO out-competes oxygen for hemoglobin binding and can displace oxygen from hemoglobin. Additionally, binding of CO to hemoglobin changes the structure of that molecule toward the relaxed state, making it more diffi cult
