A team of researchers from Wake Forest University, the National Institutes of Health and other institutions has discovered a previously undetected chemical process within the oxygen-carrying molecule ...

Most biological processes are carried out by complexes of multiple proteins that work together to carry out some function. How these complicated structures could have evolved is one of modern ...

Hemoglobin, long celebrated for ferrying oxygen in red blood cells, has now been revealed to play an overlooked—and potentially game-changing—antioxidant role in the brain. "The key was to uncover ...

Hemoglobin functions as a tetrameric oxygen carrier whose capacity to bind and release oxygen hinges on allosteric transitions between tense (T) and relaxed (R) quaternary states. A network of ...
