Q:Is all the inorganic salts in the body related to life activities?: Sugar is the most important material for the human body, all the activities of the human body, including learning, walking, digestion and breathing, etc., which are the most important substances in the human body. Consumption of energy (about 70%) mainly from the carbohydrates, fat is the body of the energy material, the protein is the basic material of human cells, but also to provide energy, vitamins are neither the main raw material of the organization, nor the supply of energy Material, but it has an important role in the life activities of the human body; inorganic salts constitute an important raw material of human tissue, water is the main component of cells. Which protein, sugar, fat, vitamins can burn for organic matter, and water, inorganic salts can not burn as inorganic.

Q:Inorganic salts are not nutritious: Nutritional substances are sugar protein fat three nutrients

Q:Sodium bicarbonate is not an inorganic salt: Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt

Q:What is the use of inorganic salts and organic salts?: The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.

Q:After a lot of sweating, the amount of drink with inorganic salt drink right?: It is best to drink this kind of drink, which contains sodium and potassium, and when the body after a lot of exercise will consume a lot of potassium, leaving the body feel weak, this drink can quickly add the body Electrolyte, need to note that before the exercise 1-2 hours, during exercise and after exercise have to drink

Q:Common inorganic salt ions will appear when the corresponding symptoms: Iron ion: iron deficiency anemia

Q:As if there are two kinds of nitrogen, phosphorus and potassium, hoping to get answers and explain their respective roles: (N) Nutrition: Nitrogen is necessary for the growth and development of plants. Usually, the total amount of nitrogen in plants is not too high, such as 1.0-2.0% of the whole plant. The plant is a plant with high nitrogen content, and the nitrogen content in the plant leaves is about 3.5-5.0% of its dry weight.The nitrogen is mainly absorbed in the form of ammonium nitrogen and nitrate nitrogen, and some small molecules of organic nitrogen Such as urea can also be absorbed by plants.Now is the main component of protein, accounting for about 16-18% of the protein content in the cytoplasm and the nucleus are containing all the enzymes are also the main body of the protein.In addition, the nucleic acid, Phospholipids, chlorophyll, coenzyme and other compounds contain nitrogen

Q:Are fruits and vegetables inactive?: Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. Apple, pipa, durian, citrus, Watermelon, kumquat, peanuts, I know so much. Oh, there are: lotus lotus which contain inorganic salts

Q:What is an inorganic salt?: Inorganic salts are not just salts of carbon-free salts, and some salts containing carbon are apparently also inorganic salts such as K2CO3, sodium bicarbonate, etc.

Q:What is the difference between organic salt and inorganic salt?: one is organic while the other is inorganic
