Encyclopedia Editors Encyclopedia editors oversee areas of study in which they have extensive knowledge, either from years of experience gained working on that content or through study for an advanced degree. They write new content and verify and edit content received from contributors.

Basic Metabolic Panel

Potassium (K), a chemical element in group 1 (Ia) on the periodic table, an alkali metal group, is very necessary for plant and animal life. Potassium was the first metal to be isolated via electrolysis, by the English chemist Sir Humphry Davy, when he obtained the element (1807) by decomposing molten potassium hydroxide (KOH) with a voltaic battery.

Potassium metal is soft and white with a silvery sheen, has a low melting point, and is a good conductor of heat and electricity. Potassium gives the flame a lavender color, and the steam is green. It is the seventh most abundant element in the Earth’s crust, accounting for 2.6 percent of its mass.

The potassium content in the Dead Sea is estimated to be around 1.7 percent potassium chloride, and many other salty waters are rich in potassium. Effluent from certain salt factories may contain up to 40 grams per liter of potassium chloride and is used as a source of potassium.

Most potassium occurs in igneous rocks, shales, and sediments in minerals such as muscovite feldspars and water-insoluble orthoclase; This makes potassium difficult to obtain. Consequently, most commercial potassium compounds (often called potash) are obtained via electrolysis of soluble potassium compounds, such as carnallite (KMgCl

Hyperkalemia: Symptoms, Treatment Overview

Potassium is produced through the reduction of sodium from molten potassium chloride, KCl, at 870 °C (1,600 °F). Melted KCl is continuously fed into a packed distillation column while sodium vapor is passed through the column. By condensing the more volatile potassium at the top of the distillation tower, the Na + KCl → K + NaCl reaction is forced to the right. Attempts to devise a commercial electrolytic potassium production scheme were unsuccessful because there were few additional salts that could reduce the melting point of potassium chloride to a temperature at which electrolysis was efficient.

There is little commercial demand for potassium metal itself, and most of it is converted by direct combustion in dry air to potassium superoxide, KO

, which is used in respiratory equipment because it liberates oxygen and removes carbon dioxide and water vapor. (Potassium superoxide is a yellow solid consisting of K

Ion. This metal can also be formed through the oxidation of potassium amalgam with dry air or oxygen.) This metal is also used as an alloy with sodium as a liquid metal heat transfer medium. Potassium reacts strongly with water, releasing hydrogen (which burns) and forming a solution of potassium hydroxide, KOH.

Sodium-potassium (NaK) alloys are used to some extent as heat transfer coolants in some fast breeder nuclear reactors and experimentally in gas turbine power plants. This alloy is also used as a catalyst or reducing agent in organic synthesis.

In addition to potassium alloys with lithium and sodium, alloys with other alkali metals are also known. Perfect miscibility occurs in the potassium-rubidium and potassium-cesium binary systems. The latter system forms an alloy that melts at about −38 °C (−36 °F). Modification of the system with the addition of sodium results in ternary eutectic melting at a temperature of about −78 °C (−108 °F). The composition of this alloy is 3 percent sodium, 24 percent potassium, and 73 percent cesium. Potassium is essentially immiscible with all alkaline earth metals, as well as with zinc, aluminum and cadmium.

) is needed by all plants and animals. Plants need it for photosynthesis, regulation of osmosis and growth, and activation of enzymes. Each animal has maintained potassium levels and a relatively fixed potassium-sodium ratio. Potassium is the major inorganic cation in living cells, and sodium is the most abundant cation in extracellular fluid. In higher animals, complexan is selective for Na

Acts on cell membranes to provide “active transport.” This active transport transmits electrochemical impulses to nerve and muscle fibers and balances the activities of nutrient intake and waste removal from cells. Too little or too much potassium in the body is fatal; However, potassium in the soil ensures the presence of this indispensable element in the diet.

Effect Of Salt Substitution On Cardiovascular Events And Death

The potassium content in plants varies greatly, although it usually ranges from 0.5–2 percent of dry weight. In humans the potassium ratio between cells and plasma is approximately 27:1. The potassium content in muscle tissue is approximately 0.3 percent, while the potassium content in blood serum is around 0.01–0.02 percent. The dietary requirement for normal growth is approximately 3.3 grams (0.12 ounces) of potassium per day, but consumption of more than 20 grams (0.7 ounces) of potassium produces different physiological effects. Excess potassium is excreted in the urine, and large amounts of potassium may be lost in sweating.

Natural potassium consists of three isotopes: potassium-39 (93.26 percent), potassium-41 (6.73 percent), and radioactive potassium-40 (about 0.01 percent); several artificial isotopes have also been prepared. Potassium-39 is usually about 13.5 times more abundant than potassium-41. Natural radioactivity of potassium is caused by beta radiation from the isotope potassium-40 (10

Electrons, so they usually have an oxidation state of +1 in their compounds, even if they contain anions, KObjective: To test whether serum potassium and sodium levels are associated with long-term cancer risk in initially healthy men.

Patients and Methods: A 1994 cohort of healthy men who did not use drugs, aged 40-59 years, were followed for cancer for 40 years of follow-up. The association between fasting electrolyte levels and cancer risk was assessed with incidence rates and Cox proportional hazards models.

Results: Potassium, but not sodium, was linearly associated with cancer risk. This association remained significant after adjustment for several potential confounders, and also after the first 10 years of follow-up were excluded. Cancer risk across sites adjusted for age increased by 16% for each SD increase in potassium levels. Men with hyperkalemia showed a 40% higher incidence rate than men with normal potassium levels.

Conclusion: Fasting serum potassium levels in healthy men are positively associated with long-term cancer risk. Potassium or potassium ion channels may play a role in cell proliferation or differentiation. These findings may imply future cancer strategies to target individuals with high serum potassium levels.

Potassium and sodium electrolyte levels have been a topic of interest in cancer etiology for many years. In the 1980s, several observations raised suspicions that cancer was related to diet or the potassium and sodium content in the body.

Recently, the properties and function of certain ion channels have been suggested to be involved in tumor development and progression.

Additionally, increased potassium levels and decreased sodium levels have been found in patients with various types of cancer,

Thus, extracellular electrolyte concentrations may be related to cancer diagnosis, either because electrolyte composition may facilitate cancer development or as a result of undetected cancer disease. However, the relationship between potassium or sodium and the development of cancer has not been studied in healthy individuals.

In this study, we aimed to prospectively examine the association between fasting serum sodium and potassium levels in initially healthy middle-aged adults and cancer incidence over 40 years of follow-up.

The Oslo Ischemia Study was a comprehensive health survey conducted in 1972 that aimed to determine risk factors for coronary heart disease and other cardiovascular diseases in a healthy male population. A total of 2,341 male employees at five companies in Oslo, Norway, aged 40–59 years, were invited to participate in the period August 1972–March 1975. Inclusion in the study required the absence of any disorders and no use of drugs for 14 years final. day. Among those invited, 2014 (86%) agreed to participate and completed the study protocol. At the time of inclusion, all participants underwent a comprehensive review of medical history, clinical and physical examination (including height and weight measurements), a panel of blood tests, and a maximal exercise tolerance cycling test. In addition, information regarding lifestyle variables (e.g. smoking habits) was collected through questionnaires. Detailed selection and implementation procedures have been reported previously.
