- Q: TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?
- False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.
- Q: Nutritional characteristics of carbohydrates and inorganic salts in vegetables
- Inorganic salts: its rich, such as calcium, phosphorus, iron, potassium, sodium magnesium, copper, is an important source of inorganic salts, to maintain the body's role in acid-base balance play an important role. Green leafy vegetables generally contain more than 100mg / 100g. But should pay attention to the removal of part of the oxalic acid during cooking, may be conducive to the absorption of inorganic salts.
- Q: For patients with ulcerative colitis, which inorganic salt foods can eat?
- Inorganic salts with water-soluble and can not oxidize the combustion and other properties, plays a role in maintaining the body's acid-base balance and metabolism.
- Q: Several inorganic salts are lacking in symptoms and food sources
- Ingredients of iodine-containing inorganic salts (trace): seaweed, jellyfish, corn, mussels, etc.
- Q: Inorganic salt function
- The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.
- Q: Does the lack of inorganic salts cause convulsions?
- The lack of important substances in the salt body is indeed the use of salt to protect the health of important substances than the calcium and phosphorus main body bone calcium blood coagulation muscle contraction and nerve cell regulation very important phosphorus calcium with the same function of food are preserved phosphorus body lack of calcium muscle spasms Can be rash dyspnea gastrointestinal paralysis and other body no phosphorus calcium calcium phosphate can be used to make bone calcium and phosphorus with a reasonable reason to play its role in the use of salt my body's non-essential body about 50 grams of salt according to 0 --- 2 5 grams To follow the excreta outside the body need to be added or otherwise the body of the production capacity of the body is extremely lack of salt can be fainting disease to speed up or even cause muscle weakness in the iron content and its role is not important in vivo iron deficiency anemia and other iron deficiency
- Q: What is the risk of low inorganic salt?
- Iodine content in the human body is much lower than 1/10000 is a trace element. Function iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases endemic goiter and local minor illnesses. Excessive symptoms iodine goiter, iodine thyrotoxicosis. Supply Adult 150ug Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
- Q: would heterotrophic organism grow well in inorganic salt media? why or why not?
- No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
- Q: therefore indigestible..that I should look for organic plant based trace mineral compounds..anyone care to comment?
- All trace minerals are "inorganic". That's what a mineral is. What the article means is that they are inorganic in the sense that the supplements just have mineral compouds, rather than being derived from a food source. That doesn't make them indigestible, but it can mean they aren't as readily absorbed. Vitamins and minerals are ALWAYS absorbed better when derived from food sources, such as eating a balanced diet, then they are by popping a supplement with a mineral compound in it. But if you need supplements, I don't know if there's such a striking difference between regular mineral supplements or "plant-based" whole food supplements. I don't doubt that whole food plant supplements are probably better, but I don't know that they're better to the degree that it makes the regular supplements "terrible". The best source is STILL diet.
- Q: Is iodized salt inorganic or organic?
- "Iodized salt" is sodium chloride which contains minute amounts of iodine-containing salts. The most commonly added iodine salts are: potassium iodate, potassium iodide, sodium iodate, and sodium iodide. All of these compounds are inorganic. By the way, while methyl iodide is organic, it is not a salt.
