while covalent compounds are insoluble in water. Solids like glass and plastic melt when heated to a very high temperature, but they never dissolve in any liquid. The chemical properties of soluble substances are different
For example, glycemic index of a given food may increase with ripeness, food processing and cooking time and decrease with co-ingestion of fats, proteins or insoluble fiber (whole grains). Low-Carbohydrate (Ketogenic) Diet There is SOME EVIDENCE that a low-carbohydrate diet can be effective in...
these compounds are water-insoluble. Water molecules are not completely neutral; they have a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms. Because covalent compounds are made up of neutral or minorly charged molecules, they are not strongly attracted...
(di-/tri), waxes, steroids, and phospholipids. Lipids are the ester of theglyceroland fatty acid molecules. Lipid molecules are of various lengths and different degrees of saturation that end with the free carboxylic acid group. Lipids are water-insoluble and soluble in non-polar. Thus, ...
The lipophilic core of the globules can be used as a polysoap-like microphase which is able to temporarily accommodate various water-insoluble hydrophobic compounds, including reactive substrates. It is shown that drug delivery and enzyme-like catalysis can be achieved on command....
Formation of a PrecipitateA precipitate is a solid product that separates from the solution during a chemical reaction.The formation of a precipitate characterizes some reactions. A precipitate is formed when one of the products is insoluble in the solvent. For example,When...
These are insoluble in non-polar solvents These are hydrolyzed by water and liberate hydrocarbon2. σ –bonded Organometallic CompoundsA covalent bond is present between the metal atom and the carbon atom of an organic group. Metals with a low electropositive nature form this kind of bond. Non...
Cell walls of fungi containmelaninthat is high molecular weight and negatively charged pigment. Melanin is insoluble in water and acts to protect the fungal cell from stressors such as UV light, high temperature, and toxins so that it can survive inside the host cell. Melanin production is one...
In a double-replacement reaction, the positive and negative ions of two ionic compounds exchange places to form two new compounds. AB + CD → AD + CB The double-replacement reaction is of two types. a) Precipitation Reaction The formation of an insoluble solid in an aqueous solution is call...
Strong acids, strong bases, and soluble ionic compounds (usually salts) exist as dissociated ions in aqueous solution, so they are written as ions in the ionic equation. Weak acids and bases and insoluble salts are usually written using their molecular formulas because only a small amount of th...
