#In s. Impurities, being present in much lower concentration, do not saturate the solvent and so remain dissolved in the liquid. If a change in conditions (e.g. cooling) mean that the concentration is actually higher than the Saturation Point , the solution has become Supersaturated . # In Physical Chemistry when referring to surface processes, saturation denotes the degree of which a surface is full of something, e.g. Base Saturation means the fraction of Exchangeable Cations that are base cations. Similarly, in Soil chemistry soil moisture saturation means that all voids are filled with water and thus all surfaces wetted, and Nitrogen Saturation means that an ecosystem, e.g. a soil, can not store any more nitrogen #In s are saturated, and Alkene s are unsaturated. The Degree Of Unsaturation is a method of specifying the amount that a compound is partially saturated. In the modern treatment of electronic structure, unsaturated compounds are characterized by pi electron systems. The term is applied similarly to the fatty acid constituents of lipids, where the fat is described as saturated or unsaturated, depending on whether the constituent fatty acids contain carbon-carbon double bonds. Unsaturated is used when any carbon structure contains double or occasionally triple bonds. Many vegetable oils contain fatty acids with one (''monounsaturated'') or more (''polyunsaturated'') double bonds in them. #In Biochemistry the term saturation refers to the fraction of total protein Binding Site s that are occupied at any given time. edited by qwerty SEE ALSO |
