T=1RST ?[/QUOTE] It could be that Or it could be because Ethanol is obtained by fermentation using glucose produced from sugar from the hydrolysis of starch, in the presence of yeast and temperature of less than 37 °C to produce ethanol. For instance, such a process might proceed by the conversion of sucrose by the enzyme invertase into glucose and fructose, then the conversion ofglucose by the enzyme zymase into ethanol (and carbon dioxide). Several of the benign bacteria[which?] in the intestine use fermentation as a form of anaerobic metabolism. Thismetabolic reaction produces ethanol as a waste product, just like aerobic respiration produces carbon dioxide andwater. Thus, human bodies contain some quantity of alcohol endogenously produced by these bacteria. In rare cases, this can be sufficient to cause "auto-brewery syndrome" in which intoxicating quantities of alcohol are produced. Or it could be because I like getting pissed.
