| 21. | Lobsters, like snails and spiders, have blue blood due to the presence of hemocyanin which contains copper.
|
| 22. | Hemocyanin also exhibits phenol oxidase activity, but with slowed kinetics from greater steric bulk at the active site.
|
| 23. | The understanding of proteins within this superfamily would not be well understood without the extensive studies of hemocyanin in arthropods.
|
| 24. | A hemocyanin of the tarantula " Eurypelma californicum " is made up of 6 hexamers or 36 chains.
|
| 25. | The hemocyanin found in " Concholepas concholepas " blood has immunotherapeutic effects against bladder cancer in murine models.
|
| 26. | Because hemocyanin is blue, these organisms have blue blood rather than the red blood of iron-based hemoglobin.
|
| 27. | Because octopuses have hemocyanin as copper-based blood, a small change in pH can reduce oxygen carrying capacity.
|
| 28. | Like most molluscs, cephalopods use hemocyanin, a copper-containing protein, rather than hemoglobin, to transport oxygen.
|
| 29. | Because of the large size of hemocyanin, it is usually found free-floating in the blood, unlike hemoglobin.
|
| 30. | Keyhole limpet hemocyanin ( KLH ) is a known immune stimulant derived from circulating glycoproteins of the marine mollusk Megathura crenulata.
