I am a candidate for this year's Harbin City, Jiqiu the standard answer, tomorrow I will test !!!
It is the life activity of the organism. Such as: magnesium ions are ATPase activator, chloride ion is an activator of saliva enzyme.
is to maintain the cell within the acid-base balance, regulating osmotic pressure, maintaining the shape and function of cells. Such as calcium in the blood, and potassium ions.
Due to the metabolism, every day a certain amount of inorganic salts from a variety of ways excreted, and thus must be supplemented by dietary supplement. 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.
norganic 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 salt ions in the body fluid regulate the permeability of the cell membrane, control the water, maintain normal osmotic pressure and acid-base balance, and help transport the general element to the body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiologic functions, which are constituents of enzymes that make up enzymes, hormones, vitamins, proteins and nucleic acids, 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.
The distribution of inorganic salts in the human body is extremely uneven. For example, calcium and phosphorus are mostly in hard tissue such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue.
