- Q: and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^)
- I think organic compunds are anything with Carbon(C), although I really don't know.
- Q: Can inorganic salts be tested by LC / MS?
- LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
- Q: What is the inorganic salt in the egg
- Fat (g) .1 niacin (mg) .2 iron (mg 1.6
- Q: Seaweed, kelp, shrimp and other seafood, the content is more of the kind of inorganic salts
- Inorganic salts in the human body is very small, but the role is very large, if the lack of suffering from the corresponding diseases, such as iodine deficiency susceptible to big neck disease, kelp, seaweed and shrimp and other seafood iodine is rich; More calcium; spinach rich in iron; nuts, liver and other zinc more.
- 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: Does the urine and urine contain inorganic salts? Anxious
- When the blood flows through the glomerular, in addition to blood cells and macromolecules of protein, the plasma part of the water, inorganic salts, glucose and urea and other substances, can be filtered through the glomeruli into the renal capsule, the formation of urine ; When the original urine through the renal tubular, which is useful for the human body substances, including most of the water, all the glucose and part of the inorganic salt, reabsorbed by the renal tubules, and into the capillaries outside the renal tube, To the blood; in the renal tubular reabsorption at the same time, renal tubular epithelial cells will produce substances (such as ammonia) secretion into the renal tubular bureaucratic, and the original urine of other waste, such as urea, part of the water and inorganic Salt, etc. from the renal tubular effusion, the formation of urine. Therefore, plasma, urine and urine are contained in the material is water, inorganic salts, urea.
- Q: What inorganic salts are needed for seeds?
- Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid
- Q: My inorganic diet seems to be working but I am getting tired of the taste of rock salt. Should I continue?
- Its all a matter of self-preservation.
- Q: Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.
- Inorganic salts that inorganic compounds in the salt, formerly known as minerals, in biological cells generally only fresh weight of 1% to 1.5%, the current body has found more than 20 species, including a large number of elements Ca Ca, P, K Ka Sulfur, selenium, molybdenum, fluorine, chromium, cobalt, iodine and so on. Although the inorganic salt in the cell, the body content is very low, but the effect is very large, if the attention of diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, Salt to maintain a normal level.
