What are the important physiological functions of inorganic salts in cells
As a result of metabolism, every day a certain amount of inorganic salts from a variety of ways out of the body, which will be added through the diet. The metabolism of inorganic salts can be judged by analyzing the concentration of blood, hair, urine or tissue. The role of inorganic salts in the human body is interrelated. In the appropriate concentration range beneficial to the health of people and animals and plants, lack or too much can cause disease, and disease and affect its metabolism, often increase its consumption. In China, the lack of calcium, iron and iodine is more common. Selenium, fluoride and other geochemical environment with the different, both the lack of disease such as Keshan disease and Kashin-Beck disease, teeth, etc., there are too many diseases such as fluorosis and selenium poisoning.
Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salts in the body fluids regulate the permeability of the cell membrane, control the moisture, maintain normal osmotic pressure and acid-base balance, and help transport the common elements to the whole body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiological functions of constituents, hormones, vitamins, proteins and nucleic acids that make up enzymes, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.
Maintain the living activities of the organism. Such as: magnesium ions are ATPase activator, chloride ion is an activator of saliva enzyme.
Maintain intracellular acid-base balance, regulate osmotic pressure, maintain cell morphology and function. Such as: blood calcium and potassium ions.
