aldehyde

[al′dəhīd′]

Etymology: Ar, alkohl + L, dehydrogenatum, dehydrogenated

any of a large category of organic compounds derived from the oxidation of a corresponding primary alcohol, as in the conversion of ethyl alcohol to acetaldehyde, also known as ethanal. Each aldehyde is characterized by a carbonyl group (─CO─) attached directly to a hydrogen (─CHO) in its formula and can be converted into a corresponding acid by oxidation, as in the conversion of acetaldehyde to acetic acid.

aldehyde

an organic compound containing the aldehyde functional group (−CHO); that is, one with a carbonyl group (C=O) located at one end of the carbon chain. Aldehydes are formed in meat during the rancidification of fat and in the degradation of alcohols in biological materials. They have an acrid unpleasant taste and are toxic if taken in sufficient quantities. Some aldehydes (formaldehyde and glutaraldehyde) are used as disinfectants and fixatives.
