  • Nonetheless, after decades of determined effort, in 1959 a small band of scientists correctly deduced the precise structure of one of the simplest molecular machines of the cell—a molecule called myoglobin.

  • Robert Champion Jr.'s muscles were so injured that they leaked a protein called myoglobin, which was too much for his kidneys to process and could have been the cause of his death

  • There's nothing actually harmful about dark meat: The brown hue comes from a compound called myoglobin, which helps transport oxygen to the muscles so that they function efficiently.

  • Tests by Paul Jepson, an expert on whales and dolphins at the Zoological Society of London, found that the whale's renal failure was caused by the release of an oxygen-carrying muscle protein called myoglobin that had seeped into the blood from the damaged tissues of its crushed muscles.

  • The team has previously shown that after severe muscle injury, proteins such as myoglobin escape into the bloodstream and are deposited in the kidneys, which generate free-radicals that can damage cells and induce renal failure.

  • "The damaged muscles leaked out a protein called myoglobin, 'and it's too much for the kidneys to process. It causes the kidneys to fail,' which results in death, Oliver said.

    The muscle damage is called rhabdomyolysis, Oliver said.

    'Most of the time it's in (car) accidents or in people who freeze to death, and you get it in a lot of people who have prolonged seizures or in people who are in extreme physical activity like running in a marathon,' Oliver said. 'You see it in torture or child abuse and severe burns when the muscles get damaged.'"
