Q:Is the inorganic salt related to the excitement
In the natural state, both in the periphery and within the central nervous system, nerve impulses are conducted in the context of a single neuron. At the nerve tip (synaptic or on the muscle joint), nerve impulses cause the excitement or inhibition of the next cell by chemical transmission or electrical transmission.
Q:What do we get from the milk?
Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese, molybdenum. The most rare is that milk is the best source of calcium in the human body, and the proportion of calcium and phosphorus is very appropriate, conducive to the absorption of calcium. Species is complex, at least 100 kinds, the main ingredients are water, fat, phospholipids, protein, lactose, inorganic salts
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:what is the function of salts in DNA extraction?
DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.
Q:Liver cancer diet should pay attention to what issues?
Liver cancer patients have more appetite, nausea, abdominal distension and other symptoms of indigestion, it should eat digestible food, such as sour plum, fresh orange juice, fruit juice, ginger water, noodle soup, fresh millet gruel, etc. to help digestion and pain, eating Do not cool, too hot, too full.

Q:What inorganic salts and trace elements are there in rice?
Sodium (2.40 mg) of copper (2.30 micrograms) of copper (2.10 mg) of copper (1.10 mg) of zinc (1.45 mg) of copper (2.40 micrograms)
Q:Does the inorganic salt fight the mass spectrum?
Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
Q:Salt is not a kind of inorganic salt
Is an inorganic salt of inorganic salts by metal cations and non-metallic anions or ammonium ions and non-metallic anion compounds. Sodium chloride is a kind of inorganic salts!
