solute carrier family 24 (SLC24) is a type of
sodium-calcium exchanger that requires
potassium to function.
Sodium
Sodium is a
chemical element with symbol
Na (from Ancient Greek Νάτριο) and
atomic number 11. It is a soft, silver-white, highly reactive
metal. In the Periodic table it is in column 1 (
alkali metals), and shares with the other six elements in that column that it has a single electron in its outer shell, which it readily donates, creating a positively charged atom - a
cation. Its only stable
isotope is
23Na. The free metal does not occur in nature, but instead must be prepared from its compounds. Sodium is the sixth most abundant
element in the Earth's crust, and exists in numerous
minerals such as
feldspars,
sodalite and
rock salt (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the earth's minerals over eons, so that sodium (and chlorine) are the most common dissolved elements by weight in the oceans.
Na
Noun
1. a silvery soft waxy metallic element of the alkali metal group; occurs abundantly in natural compounds (especially in salt water); burns with a yellow flame and reacts violently in water; occurs in sea water and in the mineral halite (rock salt)
(synonym) sodium, atomic number 11
(hypernym) metallic element, metal
(substance-holonym) seawater, saltwater, brine
