Definition of unsaturated in English:

unsaturated

adjectiveʌnˈsatʃʊreɪtɪdˌənˈsætʃəˌreɪdəd

Chemistry

1(of organic molecules) having carbon–carbon double or triple bonds and therefore not containing the greatest possible number of hydrogen atoms.
〔化〕不饱和的
Example sentencesExamples
- When unsaturated organic compounds are used as the starting point the alcohol is made by the addition of water to the double or triple bond.
- In common with all unsaturated hydrocarbons hydrogen can be added across the double bond to produce ethane.
- Thus conjugation can occur in molecules in which the unsaturated sites are close in space but are separated by more than a single covalent bond.
- These unsaturated hydrocarbons are readily oxidised and polymerised, which can reduce the oil's shelf life.
- The unsaturated benzene ring readily reacts with halogens, rapidly discoloring bromine water.
1. 1.1 Denoting fats containing a high proportion of fatty acid molecules with at least one double bond, considered to be healthier in the diet than saturated fats.
  Example sentencesExamples
  The fat is mainly unsaturated, so potentially healthful, although all fats are equally high in calories (nine calories per gram).
  Most of the fat in peanuts is unsaturated which has been shown to lower one's LDL-cholesterol levels.
  There are two basic kinds of fat: saturated and unsaturated.
  The vitamin E requirement has long been known to increase with increased intakes of unsaturated fats.

Derivatives

unsaturation

nounʌnsatʃʊˈreɪʃ(ə)nˌənˌsætʃəˈreɪʃ(ə)n

Chemistry

The lipids in poultry exhibit a higher degree of unsaturation than red meats due to a relatively high content of phospholipids.
Example sentencesExamples
- The degree of unsaturation of fatty acids has been shown to influence several of these steps, at least in mammals.
- Qualitative changes in the levels of fatty acids also occur with cold acclimation, leading to unsaturation of the fatty acids and subsequent protection of plant membranes against freezing stress.
- The current work shows that lipid asymmetry and unsaturation both result in high critical pressures in monolayers.
- The color of a dye is due to its ability to absorb light in the visible region of the spectrum, an ability enhanced by unsaturation (presence of double bonds in the molecule) and resonance.
