(redirected from aldehyde group)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia, Hutchinson 0.01 sec.
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,
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.

Both HNS and PHZ block the reaction of the aldehyde groups with -N[H.
Because aldehyde groups are efficiently introduced into the TEMPO-oxidized pulps, the wet tensile strength improvement of the handsheets must be brought about by inter-fiber covalent bond formation.
Key statement: A process for reducing the antigenicity of sap of the Hevea Brasiliensis plant and other rubber plants by contacting with any chemical containing an aldehyde group, to cross-link antigenic proteins.
