Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?

Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.

Q:Does the apple contain inorganic salts and vitamins?

Yes, the fruit is rich in these two nutrients, especially apples

Q:What foods contain zinc-containing inorganic salts

1st: oysters (71.2 / 100g / 100g)

Q:Inorganic salt of the inorganic salt function

Participate in and maintain the metabolic activity of the organism.

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:I had asked a similar question on GC operation last week, but for different kinds of compounds.For my biochem research project at school, I'm testing the ability of a species of bacteria to biodegrade alcohols found in gasoline (methanol, ethanol, isopropyl, tert-butyl and cyclohexanol). The bacteria is growing in a solution of minute amounts of alcohols and Mineral Medium, which is basically just water and dissolved inorganic salts (CaCl2, KH2PO4, NH4NO3 and MgSO4).I know GC's are primarily used to separate organic mixtures. Can a GC separate organic compounds dissolved in salt water? Is it safe to put salt water in a GC? Or would I have to do an extraction to separate the alcohols and run the organic extract through the GC?

Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.

Q:What fruit contains more minerals?

Watermelon fruit contains 90% or so, so there are "watermelon," said watermelon contains a variety of nutrients and chemical substances. Watermelon pulp contains protein, sugar, crude fiber, potassium, phosphorus, calcium, iron, sodium, magnesium Chlorine, niacin, vitamin A, vitamin B1 and vitamin B2 in the watermelon juice also contains citrulline, alanine and glutamic acid and other amino acids, malic acid and other organic acids, pectin and a small amount of glycosides, and Medlar, cinnamon and other alkaloids and so on.

Q:Inorganic salts are not nutritious

Nutritional substances are sugar protein fat three nutrients

Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolytes are needed for metabolic reactions.

Which "inorganic salts" are you talking about? There are hundreds!
