All organisms produce alcohol in small amounts by several pathways, primarily through fatty acid synthesis, [70] glycerolipid metabolism, [71] and bile acid biosynthesis pathways. [72] Fermentation is a biochemical process during which yeast and certain bacteria convert sugars to ethanol, carbon dioxide, as well as other metabolic byproducts.
Auto-brewery syndrome (ABS) (also known as gut fermentation syndrome, endogenous ethanol fermentation or drunkenness disease) is a condition characterized by the fermentation of ingested carbohydrates in the gastrointestinal tract of the body caused by bacteria or fungi. [1]
Tecoma stans is a nontoxic plant, but honey from its flowers is poisonous. [36] [37] Plants including Rhododendron and heathers produce the neurotoxin grayanotoxin. This is toxic to humans but not to bees. Honey from these flowers can be psychoactive, or even toxic to humans. [38] Honey can ferment and produce ethanol. Animals, such as birds ...
These yeasts will produce ethanol even under aerobic conditions, if they are provided with the right kind of nutrition. During batch fermentation, the rate of ethanol production per milligram of cell protein is maximal for a brief period early in this process and declines progressively as ethanol accumulates in the surrounding broth.
[6] [7] A mild flushing reaction occurs when the body metabolizes alcohol more quickly into acetaldehyde, a toxic metabolite. [5] [8] A more severe flushing reaction occurs when the body metabolizes the acetaldehyde more slowly, generally due to an inactive aldehyde dehydrogenase enzyme. Both of those conditions—faster conversion of alcohol ...
The main alcohol dehydrogenase in yeast is larger than the human one, consisting of four rather than just two subunits. It also contains zinc at its catalytic site. Together with the zinc-containing alcohol dehydrogenases of animals and humans, these enzymes from yeasts and many bacteria form the family of "long-chain"-alcohol dehydrogenases.

[51] [52] [53] Alcohol passes easily from the mother's bloodstream through the placenta and into the bloodstream of the fetus, [54] which interferes with brain and organ development. [55] Alcohol can affect the fetus at any stage during pregnancy, but the level of risk depends on the amount and frequency of alcohol consumed. [55]
