  2. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are a common motif in many ...

  3. Rancidification - Wikipedia

    en.wikipedia.org/wiki/Rancidification

    Rancidification is the process of complete or incomplete autoxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action, producing short-chain aldehydes, ketones and free fatty acids. [1] When these processes occur in food, undesirable odors and flavors can result.

    alkyne (unsaturated) vs alkane (saturated) arene (unsaturated) vs cycloalkane (saturated) For organic compounds containing heteroatoms (other than C and H), the list of unsaturated groups is long but some common types are: carbonyl, e.g. ketones, aldehydes, esters, carboxylic acids (unsaturated) vs alcohol or ether (saturated) nitrile ...

  5. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Aliphatic compounds can be saturated, joined by single bonds (), or unsaturated, with double bonds or triple bonds ().If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound.

  6. Crotonaldehyde - Wikipedia

    As an unsaturated aldehyde, crotonaldehyde is a versatile intermediate in organic synthesis. ... 3-methoxybutanol and the food preservative Sorbic acid.

  7. α,β-Unsaturated carbonyl compound - Wikipedia

    en.wikipedia.org/wiki/Α,β-Unsaturated_carbonyl...

    An enal (or alkenal) is an organic compound containing both alkene and aldehyde functional groups. In an α,β-unsaturated enal, the alkene is conjugated to the carbonyl group of the aldehyde (formyl group). [3] The simplest enal is acrolein (CH 2 =CHCHO). Other examples include cis-3-hexenal (essence of mowed lawns) and cinnamaldehyde (essence ...

  8. Acrolein - Wikipedia

    en.wikipedia.org/wiki/Acrolein

    Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colorless liquid with a foul and acrid aroma. It is a colorless liquid with a foul and acrid aroma. The smell of burnt fat (as when cooking oil is heated to its smoke point ) is caused by glycerol in the burning fat breaking down into acrolein.
