Alcohol is eliminated from the body by various metabolic mechanisms. The primary enzymes involved are aldehyde dehydrogenase (ALDH), alcohol dehydrogenase (ADH), cytochrome P450 (CYP2E1), and catalase. Variations in the genes for these enzymes have ...
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.
Alcohol is not considered to be a nutrient (because it’s not required by the body to perform its basic functions), but it does provide 7 calories of energy for every gram we consume. By the way, “non-alcoholic” doesn’t mean a low-calorie drink.
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 ...

5 wrz 2022 · Small Intestine: Anatomy → absorbed into the bloodstream (due to solubility in water) Spreads into intracellular and extracellular spaces, including fat tissue. Women will typically have a higher blood alcohol level (given a fixed quantity of ethanol) than men due to a higher percentage of body fat
Macronutrient & Alcohol Metabolism. Now that we have digested, taken up, absorbed, and transported the macronutrients, the next step is to learn how these macronutrients are metabolized. Alcohol is also included at the end of this chapter, even though it is not a macronutrient. Sections: 6.1 Metabolism Basics. 6.2 Carbohydrate Metabolism.
