[dr.satan (OP)]

I was wondering today whether it would be possible to isolate myoglobin from the blood of a deep diving sea mammal, and cultivate it to inject into humans - therefore giving us a possibility of staying underwater longer - a helpful remedy for one of the harry potter tasks in the 4th film/book!!!! not that i am interested just happen to know that..... [] [] [] anyway, anybody that knows, please share, because i would love to stay underwater for a long time without a big o2 tank. [O8)]

It's actually not in the myoglobin, Dr. Satan, your evil-ness. It's all in the ability to regulate your metabolism and how your brain uses up oxygen... Try these two great resources: typhoon.wcp.muohio.edu/Boardman/GLG244/Presentations/04Dec/Diving.ppt AND
