Chloride in biology

Chloride is a type of essential mineral and an electrolyte in the body, meaning it helps conduct electrical signals in cells. It primarily exists as negatively charged ions (anions) and plays a vital role in maintaining the body’s fluid balance, regulating blood pressure, and ensuring proper pH levels. Chloride works closely with other electrolytes like sodium and potassium to support nerve function, digestion (by forming hydrochloric acid in the stomach), and overall cellular activity. It’s obtained through the diet, mainly from salt (sodium chloride), and is balanced through the kidneys to keep health in check.
