Potassium Ion Channels

Some articles on potassium ion channels, potassium, ion, potassium ions, ions:

Orexin-A - Mechanism
... Tests show a class of potassium ion channels that are porelike proteins in the cell membrane and they affect the cellular responses by controlling the flow of potassium ... The exact mechanism of the potassium ion channels is unknown, but the experiments show that the absence of glucose inhibited the orexin neurons by acting on this class of potassium ...
Potassium Channel - Structure - Selectivity Filter
... Potassium ion channels remove the hydration shell from the ion when it enters the selectivity filter ... similar to a water-solvating shell around each potassium binding site ... The distance between the carbonyl oxygens and potassium ions in the binding sites of the selectivity filter is the same as between water oxygens in the ...

The effective hydrated radius of the ion, a is the radius of the ion and its closely bound water molecules ... Large ions and less highly charged ions bind water less tightly and have smaller hydrated radii than smaller, more highly charged ions ...

Famous quotes containing the word channels:

    People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.
    William Faulkner (1897–1962)
