acetaldehyde
Acetaldehyde: A colorless, flammable liquid used in the manufacture of acetic acid, perfumes, and flavors. It is also an intermediate in the metabolism of alcohol. It has a general narcotic action and also causes irritation of mucous membranes. Large doses may cause death from respiratory paralysis.. acetaldehyde : The aldehyde formed from acetic acid by reduction of the carboxy group. It is the most abundant carcinogen in tobacco smoke.. aldehyde : A compound RC(=O)H, in which a carbonyl group is bonded to one hydrogen atom and to one R group.. acetyl group : A group, formally derived from acetic acid by dehydroxylation, which is fundamental to the biochemistry of all forms of life.
