He found it quite remarkable that when paraldehyde was heated with a trace of the same acid, the reaction went the other way, recreating acetaldehyde. [ 38 ] Although vinyl alcohol is a polymeric form of acetaldehyde ( § Tautomerization to vinyl alcohol ), polyvinyl alcohol cannot be produced from acetaldehyde.
Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
The enzyme acetaldehyde dehydrogenase (aldehyde dehydrogenase 2 family ALDH2, EC 1.2.1.3) then converts the acetaldehyde into the non-toxic acetate ion (commonly found in acetic acid or vinegar). [4] [6] This ion is in turn is broken down into carbon dioxide and water. [4]
Plenty of factors influence how damaging acetaldehyde is to the body, Wakeman says. The most obvious is the amount of alcohol consumed; a heavy drinker will be exposed to more acetaldehyde than a ...
Minute quantity amounts (average 196 ppb) of endogenous ethanol and acetaldehyde were found in the exhaled breath of healthy volunteers. [98] Auto-brewery syndrome, also known as gut fermentation syndrome, is a rare medical condition in which intoxicating quantities of ethanol are produced through endogenous fermentation within the digestive ...

Vitamin E acetate is a different chemical than the vitamin E found naturally in foods and in supplements. Vitamin E is safe to consume as a food or supplement up to 1,000 milligrams daily ...
The enzyme responsible for the conversion of acetaldehyde to acetate, however, remains unaffected, which leads to differential rates of substrate catalysis and causes a buildup of toxic acetaldehyde, causing cell damage. [7] This provides some protection against excessive alcohol consumption and alcohol dependence (alcoholism).
