Production of acetaldehyde from ethyl alcohol

Author: vxfd

August undefined, 2024

Ethanol, an alcohol found in nature and in alcoholic drinks, is metabolized through a complex catabolic metabolic pathway. In humans, several enzymes are involved in processing ethanol first into acetaldehyde and further into acetic acid and acetyl-CoA. Once acetyl-CoA is formed, it becomes a substrate for the citric acid cycle ultimately producing cellular energy and releasing water and carbon dioxide. Due to differences in enzyme presence and availability, human adults … WebbThe production of vinegar actually involves two fermentation processes- the first utilizing yeast to produce alcohol from sugar and the second utilizing acetic acid bacteria to oxidize ethyl alcohol acetic acid through acetaldehyde (Fig. 4.7).
