aldehyde
/ˈaldɪhʌɪd
/noun Chemistry
An organic compound containing the group —CHO, formed by the oxidation of alcohols. Typical aldehydes include methanal (formaldehyde) and ethanal (acetaldehyde).Water, ethanol, volatile organic acids, aldehydes, esters, acetals, and ketones, many of them powerfully aromatic, are among the azeotrope components in wines....
- Included among these compounds are some of the best known of all chemical families, including the hydrocarbons, alcohols, ethers, aldehydes and ketones, and organic acids.
- Over time, however, it oxidizes and chemically degrades to form alcohols, ketones, aldehydes, acids and esters.
Derivatives
aldehydic
- Reactions that occur between the aldehydic groups and other amino acids of adjoining molecules lead to cross-links between the molecules and the self-assembly into fibers.
- The aldehydic proton gives a strongly deshielded resonance signal in the H - 1 NMR spectrum.
- The components have high absorption characteristics resulting from the presence of carboxylic, hydroxylic, and aldehydic functional groups.
Origin
Mid 19th century: shortened from Latin alcohol dehydrogenatum 'alcohol deprived of hydrogen'.
