Metabolite IDPAMDB000573
Identification
Name: Chloride
Description:The chloride ion is formed when the element chlorine picks up one electron to form an anion (negatively-charged ion) Cl. Chloride is an important anion in all living systems (being part of NaCl and KCl) and cells actively transport chloride ions to help maintain an appropriate ion balance.
