About Coccodrillo hemoglobin?
The world of athletics has reacted with a mixture of skepticism and derision when he learned that the famous Chinese running coach Ma Junren was with his world-champion athletes turtles’ blood, in the hope of improving their performance, but Scientists in Cambridge, England, has recently learned that a turtle-blood cocktail may not laughing matter. This is what they have found that the blood of another reptile – the crocodile – may improve athletic performance.
The link between performance and blood of the crocodile is not so strange, because for years scientists have admired the ability of crocodiles in order to stay in water for over an hour without a single sip of fresh air. The crocodiles’ condition for the supply of fresh oxygen is so small that the animals sometimes squamous simply drag their prey under water, drowning their hapless victims, without the need for killing their powerful jaws crunch.
Curiously, crocodiles can stay under water for long periods, even if their tissues are very low levels of myoglobin, a protein that is unique and allows oxygen stores other animals such as whales and seals to stay in deep brackish water for periods of long time. The crocodiles’ low oxygen supply can occur because the oxygen in the blood protein, hemoglobin, functions in a unique way. What happens is that the crocodiles hold their breath under water, carbon dioxide accumulates in their blood is too high. Carbon dioxide dissolves in the form of bicarbonate ions. These bicarbonate ions immediately stopped on a portion of the crocodiles’ hemoglobin molecules, so that the release of hemoglobin for oxygen. These can then Rush oxygen in tissue, so it is not necessary that the underwater world of reptiles at the surface. This effect could be a big advantage for athletes with human crocodile hemoglobin in their red blood cells (hemoglobin people have disappeared crocodilean the key amino acids, the affinity of bicarbonate). As such, athletes vigorously exercised, the excess bicarbonate automatically attached to the hemoglobin Croc and “push” of supplementary oxygen in the muscles, the additional energy and stamina. Instead of sputtering oxygen limiting the intensity with which athletes crocodile human hemoglobin would “devour” their opponents.
Cool, Cambridge scientists have been able to determine the exact “docking site” for a crocodile hemoglobin bicarbonate. Then mild bacterial cells to produce more copies of this instrument and are transplanted into human hemoglobin. In essence, scientists have had a new type of hemoglobin – part human, part crocodile – that would be very effective for the release of oxygen in human tissues. In this new medical approach hemoglobin is an advantage for patients who have problems enough oxygen to their tissues (people with emphysema could benefit substantially). In the field of athletics, the hybrid hemoglobin may help athletes perform for an extended period of high intensity exercise.
