Physiological Effects Of Inorganic Salts

1. The distribution of inorganic salts in the body is extremely uneven. For example, most of calcium and phosphorus are in hard tissues such as bones and teeth, iron is concentrated in red blood cells, iodine is concentrated in thyroid gland, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue.
2. Inorganic salts are very important to the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, while soft tissues contain more potassium. Inorganic salt ions in body fluids regulate the permeability of cell membranes, control water, maintain normal osmotic pressure and acid-base balance, help transport common elements to the whole body, participate in nerve activity and muscle contraction, etc. Some are inorganic or organic compounds to constitute prosthetic groups of enzymes, hormones, vitamins, proteins and nucleic acids, or as activators of various enzyme systems, and participate in many important physiological functions. For example: keep the heart and brain active, help the formation of antibodies, and play a beneficial role in the human body.
3. Due to metabolism, a certain amount of inorganic salts are excreted from the body through various channels every day, so they must be supplemented through diet. The metabolism of inorganic salts can be judged by analyzing the concentration in blood, hair, urine or tissue. The effects of inorganic salts in the human body are interrelated. A suitable concentration range is beneficial to the health of people, animals and plants, lack or excess can cause disease, and disease affects its metabolism, often increasing its consumption. The deficiency of calcium, iron and iodine is more common in our country. Depending on the geochemical environment, selenium and fluorine have deficiency diseases such as Keshan disease, Kaschin-Beck disease, dirty teeth, etc., and excess diseases such as skeletal fluorosis and selenium poisoning.
4. It is to maintain the acid-base balance in the cell, regulate the osmotic pressure, and maintain the shape and function of the cell. Such as: calcium and potassium ions in the blood.
5. It is to maintain the life activities of organisms. Such as: magnesium ion is an activator of ATPase, and chloride ion is an activator of salivary enzyme.
