- Q:The presence of inorganic salts
- The presence of inorganic salts is mostly present in the ionic state in a small number of compounds
- Q:Is the inorganic salt related to the excitement
- Should be excited about conduction and inorganic salts. Membrane on both sides of the solution is conductive, in the excitement of the nerve segment and adjacent it is not between the excitement, due to the existence of potential difference in the charge movement, which is the local current. Its flow direction is: there is a positive charge outside the membrane has never excited to flow to the excitement section, the cell has a positive charge from the excited flow to the excitement section, the current direction is not excited to fiber membrane depolarization. When this current is strong enough to depolarize the segment to reach the threshold, a new nerve impulse - action potential is generated.
- Q:The power of the water and inorganic salts in the plant is derived from the action of the plant
- The main process is: soil moisture → root hair → root catheter → stem catheter → leaf catheter → stomata → atmosphere.
- Q:Inorganic salts are not nutritious
- Nutritional substances are sugar protein fat three nutrients
- Q:Eat what food can add inorganic salt
- Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. According to their content in the body how much can be divided into constant elements and trace elements two categories. The body is actually composed of various elements (macro and trace). Many of these mineral elements are essential components of the enzyme, which can regulate a variety of physiological functions (such as maintaining osmotic pressure, oxygen transport, muscle contraction, nervous system integrity), but also tissue and bone growth and maintenance necessary. Some (such as calcium, phosphorus, sodium, magnesium, sulfur, chloride) content is large, while others are only trace. Human essential trace elements are cobalt (such as vitamin B12), copper, fluorine, iodine, iron, zinc, chromium, selenium, manganese, molybdenum In terms of its impact on experimental animals, nickel, tin and arsenic should also be considered necessary. Most minerals (except zinc) are widely distributed in a variety of foods and can be fully supplemented by balanced and diversified diets. However, there is a need for additional supplements to patients who have been relying on intravenous nutrition for long periods of time, infants and older persons, or because of the lack of regionalities caused by soil and water quality.
- Q:What is the inorganic salt in the egg
- Calories (kcal) 60 thiamine (mg) .04 calcium (mg) 9
- Q:therefore indigestible..that I should look for organic plant based trace mineral compounds..anyone care to comment?
- Inorganic does not mean indigestible, but plant derived trace minerals are the best form to take because they have been broken down by soil micro-organisms and predigested by plants, making them much more bioavailable than minerals which have not. I use Liquid Life trace minerals. EDIT: The best source would definitely be diet except that our soils have had a whopping 85% mineral depletion over the past hundred years thanks to over-farming. Your great grandma's bowl of spinach had eight times the nutrition that the bowl you eat today has.
- Q:What is the disease of inorganic salt crystals?
- But if the urine turbidity, but also accompanied by fever, low back pain, increased frequency of urination and other phenomena, there may be inflammation of the urinary system, should go to the hospital for timely diagnosis and treatment of doctors.
- 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...
