The effects of alcohol (i.e., ethanol) on various tissues depend on its concentration in the blood (blood alcohol concentration [BAC]) over time. BAC is determined by how quickly alcohol is absorbed, distributed, metabolized, and excreted.
Alcoholic drinks are a major source of energy—for example, six pints of beer contain about 500 kcal and half a litre of whisky contains 1650 kcal. The daily energy requirement for a moderately active man is 3000 kcal and for a woman 2200 kcal.
6 sty 2005 · It is a small, water soluble molecule that is relatively slowly absorbed from the stomach, more rapidly absorbed from the small intestine, and freely distributed throughout the body. Alcoholic drinks are a major source of energy—for example, six pints of beer contain about 500 kcal and half a litre of whisky contains 1650 kcal.
20 maj 2019 · Once in the bloodstream, ethanol is distributed into the total body water (TBW) compartment, which comprises ~55–60% of body weight in nonobese males and ~50–55% in females. The volume of distribution (V d) of ethanol depends on a person's age, gender, and degree of adiposity (ratio of fat to lean tissue).
22 lut 2022 · The body transforms the calories from the alcohol into fat, which is stored as droplets of fat in the liver. In its initial phase, a fatty liver usually is not a problem, and it can be reversed if the person stops drinking. Alcoholic hepatitis is the second stage of liver disease. The liver becomes inflamed, with symptoms that include redness ...
There are three ways that alcohol is metabolized in the body. Catalase – an enzyme that we will cover again in the antioxidants section. Catalase is estimated to metabolize less than 2% of ethanol, so it is not shown below or discussed further4.
