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:the absorption of inorganic salts is how to absorb the form
Absorbed in an ionic state.
Q:Inorganic salt effect
Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable.
Q:Chemical formula The longest inorganic salt
Is this meaningful?
Q:How does inorganic salts maintain osmotic pressure and pH
Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
Q:After running the training is best to drink what drinks add inorganic salt
You say drink, personally feel good luck!
Q:Definition of inorganic salts
There are about 21 kinds of elements which have important physiological functions in the body. Among them, calcium, magnesium, potassium, sodium, phosphorus, sulfur and chlorine are more and more, and the amount of inorganic compounds is more Iron, copper, iodine, zinc, manganese, selenium, fluorine, chromium, nickel, molybdenum, silicon, tin, vanadium and cobalt content is extremely small, called trace elements .2, inorganic compounds in the general name of the salt. Formerly known as "minerals." Some elements of inorganic salts for the human essential nutrients, including potassium, sodium, calcium, phosphorus, iron, iodine and other 20 kinds of elements. With the maintenance of cells and liquid normal osmotic pressure, maintenance of neuromuscular excitement As a variety of acid system activator; constitute the ester of the base; hormones, vitamins, nucleic acid composition and regulate the body's acid and alkali balance and other important physiological functions. Increased or lack of disease, such as hyperkalemia, The explanation of the "inorganic salts" in the academic literature
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:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
to maintain the body's acid-base balance
Q:Is urea an inorganic salt?
Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.
