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.
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.
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
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.
20 maj 2019 · Figure 1 shows a schematic diagram illustrating the fate of ethanol in the body resulting in a BAC profile, passage through the BBB, and eliciting pharmacological effects.
9 cze 2021 · Alcohol is not a nutrient, but it does contain calories – 7 kcal/g. Calories come from alcohol itself, but also from the other ingredients that are often included in alcoholic drinks, such as juices and mixers.
14 sie 2020 · For example, someone who weighs 180 lbs will absorb 9-16 grams of alcohol per hour while someone weighing 120 lbs will absorb 6-10 grams of alcohol per hour. Other factors also affect alcohol absorption.
