Alcohol is an intoxicating substance that has been present since 9,000 years ago and even dates back as far as the prehistoric Stone Age. The early Greek civilization is known to have alcoholic beverages as well because distillation was present then. The first recorded alcohol or ethanol production was during the 12th century, and it was done by the School of Salerno.
Alcohol is an organic compound with (-OH) as the hydroxyl functional group. The chemical formula of ethanol was determined and recorded first in 1808 by Nicolas Theodre de Saussere. The structured formula, however, was published by Archibald Scott Couper 50 years later.Ethanol is found in wine, beer, and other liquor. It is produced through the fermentation of yeasts, starches and sugar. Once drank, alcohol affects the nervous system and goes into the bloodstream after being absorbed by the stomach and the small intestine.
