The energy from this exothermic reaction is used to bind inorganic phosphates to ADP and convert NAD+ to NADH. The two pyruvates are then broken down into two Acetaldehyde and give off two CO2 as a waste product (2). The two Acetaldehydes are then converted to ethanol by using the H+ ions from NADH; converted NADH back into NAD+ (3).
In 1954, Lindström married Agnes Ronavec and they had four children: Karl, Peter, Michael and Brita. [1] [2] [5] Lindström taught neurosurgery at the University of California, Los Angeles. [6] [7] He also taught medicine at the University of Pittsburgh and the University of Utah. [1]
C 2 H 6 O (ethanol) is converted to C 2 H 4 O (acetaldehyde), then to C 2 H 4 O 2 (acetic acid), then to acetyl-CoA. Once acetyl-CoA is formed, it is free to enter directly into the citric acid cycle (TCA) and is converted to 2 CO 2 molecules in 8 reactions. The equations: C 2 H 6 O(ethanol) + NAD + → C 2 H 4 O(acetaldehyde) + NADH + H +

Those with ADH1B*1 have higher rates of conversion of ethanol into acetaldehyde while, people with ALDH2*2 have a slower conversion rate of acetaldehyde to acetate causing faster build up of acetaldehyde concentrations. [26] 28-45% of east Asian populations carry the ALDH2*2 allele. [9] An average liver can process 7 grams of ethanol per hour.
The term ethanol was invented in 1892, blending "ethane" with the "-ol" ending of "alcohol", which was generalized as a libfix. [ 18 ] The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks .
The French chemist, Henri Braconnot, was the first to discover that cellulose could be hydrolyzed into sugars by treatment with sulfuric acid in 1819. [9] The hydrolyzed sugar could then be processed to form ethanol through fermentation. The first commercialized ethanol production began in Germany in 1898, where acid was used to hydrolyze ...
