Alcohol Consumption - Chemistry

Chemistry

Alcohol is a general term for any organic compound in which a hydroxyl group (-O H) is bound to a carbon atom, which in turn may be bound to other carbon atoms and further hydrogens. Alcohols other than ethanol (such as propylene glycol and the sugar alcohols) appear in food and beverages. Methanol (one carbon), the propanols (three carbons giving two isomers), and the butanols (four carbons, four isomers) are all commonly found alcohols — these three toxic alcohols should never be consumed in any form.

Ethanol (CH₃CH₂OH) is the active ingredient in alcoholic beverages (although novelty inebriating drinks have been made from alternate alcohols such as 2-Methyl-2-butanol). When produced for use in a beverage, ethanol is always produced by means of fermentation, i.e., the metabolism of carbohydrates by certain species of yeast in the absence of oxygen.
