Document Summary
Alcohol sugar (glucose) + water + yeast = c2h5oh (feces of bacteria) + co2. Absynthe: up to 75% ethanol, wormwood (thujone, tannin) Ethyl alcohol (c2h5oh) natural fermentation: yeast eats sugar to produce alcohol + co2 (15% alcohol is the highest possible yield) Metabolism of alc. in stomach may account for differences in m/f drinking effects: males have more alcohol dehydrogenase in stomach lining increase first-pass metabolism. Metabolized into empty calories energy devoid or nutritional value. Only 2-8% of alcohol is excreted unchanged, other amounts escape through lungs, skin (sour breath) 90-95% is oxidized in the liver flush kidneys with water to minimize reabsorption. Increases urination in 2 ways: ingestion of fluid, suppression of adh (antidiuretic hormone) inhibits kidneys from reabsorbing water. Behavioral effects: animals ataxia, sleep, vasodilation, heat loss, humans blood level expressed as mg% Alcohol stimulates cl- intake into cell (makes more and difficult to excite) Related to the blood alcohol level (bal) alc concentration in blood.
