Acylic Alcohol (CnH2n+1OH)
Ethanol (C2H5OH)

Sugar          Acids, gases or Alcohol
Absence of the electron transport chain
Reduced carbon source, such as glucose, and makes products like lactic acid or acetate.

4.Alcoholic Fermentation:
Ethanol fermentation
Sugars        Cellular Energy+Ethanol+CO2
Anaerobic Process.
Beverages , Ethanol Fuel and Bread dough

5.Chemistry ? Sucrose (C12H22O11)         Ethanol (C2H5OH)
1sucrose           4 ethanol + 4 CO2  + 2ATP

C12H22O11 + H2O + invertase ? 2 C6H12O6

C6H12O6 + 2 ADP + 2 Pi + 2 NAD+ ? 2 CH3COCOO- + 2 ATP + 2 NADH + 2 H2O + 2 H+

6.Effect of Oxygen
Pyruvate                    Ethanol
Kluyveromyces lactis or Kluyveromyces lipolytica (anaerobic)

     Pyruvate              O2 +water

Saccharomyces cerevisiae, or fission yeast Schizosaccharomyces pombe (can work in O2)

7.Alcoholic  Beverages
Wine         The natural sugars present in grapes and other kinds of fruit.

 Now        Mash of rye, corn, or potatoes.
Clear in form ,clean tasting and clear looking.

Distilled       Cane juice/scummings of the boiled juice/treacle /molasses /lees of former distillations.
Used colloquially      intoxicating liquor.
Clear or dark in form.

12.Whiskey :
Distilled from grain, potatoes
Scotland, Ireland, and the United States.
Generally distilled from maize, rye, or wheat.
But in Scotland and Ireland it is often made from malted barley.
Brown or dark.
