In chemistry, the word alcohol refers to the chemical hydroxyl functional group. This means that the compound has a hydrogen atom attached to an oxygen atom which is then connected to a chain of carbon atoms. Nearly everything we eat is an alcohol in this sense except pure water. All saccharides (energy bearing molecules essential for human life) are sugar alcohols. The main sugar used for energy in humans is glucose, which has 5 alcohol groups on it compared to the single alcohol group on dichlorobenzyl alcohol. Glucose not named an alcohol because scientists in the past devised an arbitrary naming scheme that puts aldehyde groups above alcohols in naming and because simply saying glucose is easier than saying its full official name: (2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanal.

An important class of alcohols are the simple acyclic alcohols, the general formula for which is CnH2n+1OH. Of these ethanol (C2H5OH) is the alcohol found in alcoholic beverages; in common speech the word alcohol refers to ethanol.
