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. 3. 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 (al´d 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. |
