Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
Potassium is the major cation (K +, a positive ion) inside animal cells, while sodium (Na +) is the major cation outside animal cells.The difference between the concentrations of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential.
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
"Potassium is a mineral and an electrolyte that aids in muscle contraction and blood pressure regulation by counteracting the effects of sodium and fluid balance," Whitaker says. "It may prevent ...
Potassium chloride, also known as potassium salt, is used as a medication to treat and prevent low blood potassium. [2] Low blood potassium may occur due to vomiting, diarrhea, or certain medications. [3] The concentrated version should be diluted before use. [2] It is given by slow injection into a vein or by mouth. [4]
Fiber puts the GI tract to work. Consider limiting or avoiding whole grains, such as whole-wheat pasta, whole-grain breads , bran, barley, brown rice, rye and products with added fiber, until ...
Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
Potassium aspartate is not approved for use as a chemical in its own right (but may be approved as a component in a product covered by a group standard) in the United States [2] or European Union [3] or New Zealand [2] or Australia, [2] for treating any medical condition, [4] but is studied as an alternative to potassium chloride to treat high blood pressure (hypertension): potassium chloride ...
