Q: Are there any differences between minerals and inorganic salts?: For example, iodine in kelp, calcium lactate in sour milk, etc. These minerals are not inorganic salts.

Q: Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference: There is no essential difference, the measurement method is different, so the result is different, the former is the burning method, which is the chemical method or instrument method

Q: What fruit contains more minerals?: Papaya, also known as melon. Fruit before immature, if the knife in the fruit on a knife, it will flow out of white milk, it is also known as the melon. Papaya sweet taste, which in addition to rich sugar, but also contains vitamin A , B vitamins, vitamin C and iron, calcium, organic acids, cellulose and other nutrients. Among them, β-carotene and vitamin C content is particularly high, which is 20 times the apple, they are natural antioxidants, can Effectively prevent the cold and prevent the synthesis of carcinogenic nitrosamines, but note that the cooked papaya, β-carotene, B vitamins and vitamin C is almost completely destroyed, and no health care.

Q: Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts: , to maintain the osmotic pressure of cells, especially for the absorption of nutrients in plants have an important role.

Q: Liver cancer diet should pay attention to what issues?: Balanced diet: liver cancer patients consume more, must ensure that there is enough nutrition. The easiest way to measure the nutritional status of a patient is to maintain weight. And to maintain the normal level of weight, the best way is to maintain a balanced diet, requiring patients should eat more fresh vegetables, and half should be green leafy vegetables.

Q: Does the milk contain inorganic salts?: Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element

Q: I tried sodium and potassium carbonate and had little luck. Anyone know where to find the solubility data of inorganic salt in DMF?Thanks.: Sodium and potassium carbonate WILL dissolve in DMF. The best way to dissolve them is to... a) dry the solid inorganic salt in an oven (> 100 degrees C) overnight. b) pulverize the powder and grind several minutes with mortal and pestle. c) sonicate the mixture for several minutes...

Q: Common inorganic salt ions will appear when the corresponding symptoms: Iodine: goiter, mental and physical development disorders

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: What is the use of inorganic salts in plants? How is it discharged: Nitrogen is the constituent of chlorophyll, chlorophyll a and chlorophyll are all nitrogen compounds. Green plants for photosynthesis, so that light energy into chemical energy, the inorganic (carbon dioxide and water) into organic matter (glucose) is the role of chlorophyll. Glucose is the raw material for the synthesis of various organic substances in plants, and chlorophyll is the factory for the manufacture of "grain" for plant leaves. Nitrogen is also an integral part of vitamins and energy systems in plants. The transpiration of plants, taken away by water, is similar to human sweating
