aldehyde /al·de·hyde/ (al´dĕ-hīd)
1. any of a class of organic compounds containing the group —CHO, i.e., one with a carbonyl group (CdbondO) located at one end of the carbon chain.
2. a suffix used to denote a compound occurring in aldehyde conformation.

al·de·hyde (ld-hd)
n.
1. Any of a class of reactive organic chemical compounds obtained by oxidation of primary alcohols, characterized by the common group CHO, and used in the manufacture of resins, dyes, and organic acids.
2. See acetaldehyde.

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 [al´dĕ-hīd]
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.

aldehyde,
n hydrocarbon characterized by strong scent; antiviral, antiinflammatory, and soothing properties. Can irritate skin if administered improperly.

Aldehyde.

aldehyde (al´dhīd´),
n a large category of organic compounds derived from a corresponding alcohol by the removal of two hydrogen atoms, as in the conversion of ethyl alcohol to acetaldehyde.

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.

They correlated quality indices--color, free and total sulfur dioxide, total aldehyde and total phenol content--with spectral information derived from multivariate analyses.
The UIF resins also contained hydroxyl groups and aldehyde groups; the content of aldehyde groups in the resin increased as the amount of isobutyraldehyde increased.
The aldehyde undergoes an additional reaction known as beta elimination to produce a substance that glows bright green-or Pittsburgh Green, as the researchers termed it-under an ultraviolet (UV) lamp or microscope.
