Description

ChEBI: A monoatomic monocation obtained from potassium.

Solid

Potassium(1+) is a monoatomic monocation obtained from potassium. It has a role as a human metabolite and a cofactor. It is an alkali metal cation, an elemental potassium, a monovalent inorganic cation and a monoatomic monocation.|Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential. The balance between potassium and sodium is maintained by ion pumps in the cell membrane. The cell membrane potential created by potassium and sodium ions allows the cell generate an action potential—a "spike" of electrical discharge. The ability of cells to produce electrical discharge is critical for body functions such as neurotransmission, muscle contraction, and heart function. Potassium is also an essential mineral needed to regulate water balance, blood pressure and levels of acidity.|Potassium cation is a Potassium Salt and Osmotic Laxative. The mechanism of action of potassium cation is as an Osmotic Activity. The physiologic effect of potassium cation is by means of Increased Large Intestinal Motility and Inhibition Large Intestine Fluid/Electrolyte Absorption.

Mechanism of Action：

Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential. The balance between potassium and sodium is maintained by ion pumps in the cell membrane.
