Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
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] ABS is a rare medical condition in which intoxicating quantities of ...
The pharmacology of ethanol involves both pharmacodynamics (how it affects the body) and pharmacokinetics (how the body processes it). In the body, ethanol primarily affects the central nervous system, acting as a depressant and causing sedation, relaxation, and decreased anxiety. The complete list of mechanisms remains an area of research, but ...
Auto brewery syndrome occurs when the gastrointesintal tract converts food into alcohol. ... A low-carb and low-sugar diet can also prevent the body from producing alcohol.
This theory was corroborated by Liebig's observation that other decomposing matter, such as rotten plant and animal parts, interacted with sugar in a similar manner as yeast. That is, the decomposition of albuminous matter (i.e. water-soluble proteins) caused sugar to transform to alcohol. [4] [5] Liebig held this view until his death in 1873. [4]
In selecting mash temperature and grain-to-water ratio, a brewer can change the alcohol content, mouthfeel, aroma, and flavor of the finished beer. In some historic methods of producing alcoholic beverages, the conversion of starch to sugar starts with the brewer chewing grain to mix it with saliva. [5]
Alcohol is known to potentiate the insulin response of the human body to glucose, which, in essence, "instructs" the body to convert consumed carbohydrates into fat and to suppress carbohydrate and fat oxidation. [43] [44] Ethanol is directly processed in the liver to acetyl CoA, the same intermediate product as in glucose metabolism.
Sugar alcohols can be, and often are, produced from renewable resources.Particular feedstocks are starch, cellulose and hemicellulose; the main conversion technologies use H 2 as the reagent: hydrogenolysis, i.e. the cleavage of C−O single bonds, converting polymers to smaller molecules, and hydrogenation of C=O double bonds, converting sugars to sugar alcohols.
