Potassium channels are critical structures in biology; they selectively allow potassium ions to pass through the membrane surrounding cells. The precise gating of that channel is essential to its ...

Kaboom! Pure potassium is a highly reactive metal. Exposed to water, it explodes with a purple flame, so it's usually stored under mineral oil for safety. Because it's so reactive, potassium isn't ...

THE specific γ-activity of ordinary potassium, in the form of ‘AnalaR’ potassium chloride, has been determined by the following procedure: (1) A source of potassium-42 (obtained by the irradiation of ...

Researchers have established the structure of a crucial enzyme -- the so-called sodium-potassium pump -- which forms part of every cell in the human body. The result may pave the way for a better ...

It's not visible to the naked eye and you can't feel it, but up to 40 per cent of your body's energy goes into supplying the microscopic sodium-potassium pump with the energy it needs. The pump is ...
