In chemistry, alcohol is an organic compound and its functional group consist of crbon bonded to an -OH group. The general formula for alcohol is CnH2n+1OH. The common term of alcohol is ethanol that can be found in alcoholic beverage. Alcohol is made by a process which is known as fermantation. Alcohol fermentation is done by the yeast and some kinds of bacteria. These microorganisms convert sugars into ethyl alcohol and carbon dioxide. Alcoholic fermentation begins after glucose enters the cell. The glucose is broken down into pyruvic acid and then converted to CO2, ethanol, and energy for the cell. Fermentation is used in making bread, beer, and wine. The same microorganism is used in these three products: the common yeast or Saccharomyces Cerevisae.
The word equation for the fermentation process is:
Glucose + yeast--->alcohol+carbon dioxide

Application of Alcohol

1. Wear it
Ethanol is a common ingredient in many cosmetic. Ethanol is quite volatile so its function is to evaporate, absorbing its enthalpy change of vaporisation and cooling the skin. Furthermore, ethanol is also an ingredient in nail varnish. It acts as a slovent for the lacquer. When the solution is applied to the nails, the ethanol will evaporate and leaving a layer of laquer on the nail.
