Overview: how is alcohol metabolized by the body?
1Division of Metabolism and Health Effects, National Institute on Alcohol Abuse and Alcoholism, Bethesda, Maryland, USA.
Summary
Alcohol metabolism involves key enzymes like alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). Genetic variations in these enzymes impact alcohol consumption, dependence, and tissue damage, highlighting the need for further research.
Area of Science:
- Biochemistry
- Genetics
- Toxicology
Background:
- Alcohol is metabolized by enzymes including alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), cytochrome P450 (CYP2E1), and catalase.
- Genetic variations in these enzymes significantly affect alcohol consumption, alcohol-related tissue damage, and alcohol dependence.
Purpose of the Study:
- To summarize the metabolic pathways of alcohol elimination.
- To highlight the consequences of alcohol metabolism and identify areas for future research.
Main Methods:
- Review of existing literature on alcohol metabolism.
- Analysis of the enzymatic pathways and genetic variations involved.
Main Results:
- Alcohol metabolism generates byproducts that can lead to cellular damage, including hypoxia, adduct formation, and reactive oxygen species (ROS).
- Metabolism alters the cellular redox state (NADH/NAD+ ratio), contributing to tissue damage, fetal harm, impaired metabolic processes, cancer, and medication interactions.
Conclusions:
- Genetic variations in alcohol-metabolizing enzymes play a crucial role in alcohol's effects on the body.
- Further research is needed to fully understand and address the multifaceted consequences of alcohol metabolism.

01:19Overview of Carbohydrate Metabolism
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

01:17Drug Metabolism: Phase I Reactions
A phase I reaction is a biochemical process that introduces a functionally reactive polar group to a substance. This transformation predominantly occurs in the liver, facilitated by the cytochrome P450 system of hemoproteins situated in the lipophilic endoplasmic reticulum of cells. The metabolite generated through this process can have varying polarities. If it is sufficiently polar, it can be easily excreted in the urine due to its water compatibility. However, if the metabolite is nonpolar,...
01:24Overview of Lipid Metabolism
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

01:40Overview of Metabolism
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

01:28Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...
