Alcohol is a molecule formed when oxygen and hydrogen atoms bind with a carbon atom. Ethanol, or ethyl alcohol, is the specific type of alcohol found in alcoholic drinks. It is produced through the fermentation of grains, fruits, or vegetables, where yeast or bacteria react with the sugars in these ingredients to create ethanol and carbon dioxide. The alcohol content of a drink depends on the duration of its fermentation. In addition to ethanol, alcoholic beverages may contain various trace elements, such as potassium, magnesium, calcium, sodium, iron, copper, manganese, zinc, and more.

What You'll Learn
Alcohol is made by fermenting grains, fruits or vegetables
Alcohol is made by fermenting grains, fruits, or vegetables. This process involves yeast or bacteria reacting with the sugars in these ingredients to produce ethanol (the alcohol in the drink) and carbon dioxide (which can result in the drink having bubbles). The alcohol content of a drink depends on how long it is left to ferment.
Ethanol, also known as ethyl alcohol, is a small molecule that is the alcohol found in alcoholic beverages. It is also used in toiletries, pharmaceuticals, and fuels, and it is used to sterilize hospital instruments. The "eth-" prefix and the qualifier "ethyl" in "ethyl alcohol" were coined by Justus Liebig in 1834, derived from the German name "Aether" for the compound C 2H 5−O−C 2H 5.
In chemistry, ethanol has a variety of uses beyond alcoholic beverages. It is a solvent for substances intended for human contact or consumption, including scents, flavorings, colorings, and medicines. It also serves as a feedstock for the synthesis of other products. Additionally, ethanol has a long history as a fuel for heat, light, and internal combustion engines.
The concentration of ethanol in alcoholic beverages can be increased through fractional freezing, as seen in traditionally made Applejack. However, pure ethanol and alcoholic beverages are taxed heavily as psychoactive drugs. To avoid this tax, jurisdictions may waive it if an agent is added to the ethanol to make it unfit for consumption, creating denatured alcohol.
In addition to ethanol, alcoholic beverages contain various trace elements and compounds. For example, wines can contain anthocyanins, which contribute to their pigment, and elements such as potassium, magnesium, calcium, and sodium. The concentration of these elements can vary depending on the type of wine and its age.

Ethanol is the small molecule that results from fermentation
Alcohol is a broad term that refers to a wider class of substances in chemistry nomenclature. Ethanol, also known as ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol, is a type of alcohol. It is a volatile, flammable, colorless liquid with a pungent taste. Ethanol is a small molecule that results from the fermentation process of sugars by yeasts or petrochemical processes such as ethylene hydration.
Fermentation is a type of anaerobic metabolism that uses the redox potential of reactants to produce adenosine triphosphate (ATP) and organic end products. Organic molecules, such as glucose or other sugars, are broken down and their electrons are transferred to other organic molecules. Fermentation occurs in both prokaryotes and eukaryotes, and it is especially prevalent in prokaryotes of the phylum Bacillota. The most common fermentation products include lactate, acetate, ethanol, carbon dioxide, succinate, hydrogen, propionate, and butyrate.
Ethanol can be produced through the fermentation of starch or sugar, and it is an important source of liquid biofuel. In the United States, ethanol is commonly made from grains such as corn, wheat, and barley, while in tropical areas like Brazil, it is made from sugarcane. The process of fermentation for ethanol production involves the breakdown of sugar and starch components of renewable plant materials using yeast. This fermentation process can occur naturally in environments like overripe fruit and palm blossoms, during plant germination under anaerobic conditions, and even in human breath.
Ethanol has a long history of use, with humans discovering it not long after they learned to use fire. It has been used as an intoxicant since ancient times and was historically used as a general anesthetic. Today, ethanol has various applications, including its use in food and beverages, manufacturing processes, industrial products, and as a fuel source for lamps, stoves, and internal combustion engines.
As a central nervous system depressant, ethanol is one of the most commonly consumed psychoactive drugs globally, second only to caffeine. It is the active ingredient in alcoholic beverages and is readily available and legal for sale in many countries. However, it is important to note that ethanol metabolism can lead to the production of acetaldehyde, a known carcinogen that poses greater toxicity in humans than ethanol itself.

Alcohol affects your body and brain every time you drink
Alcohol is a molecule formed when oxygen and hydrogen atoms bind with carbon. Ethanol, a small molecule, is the alcohol found in drinks. When you drink, ethanol molecules are absorbed into your bloodstream and spread to virtually all parts of your body, including your brain.
Alcohol affects your brain's communication pathways, impairing areas that control balance, memory, speech, and judgment. It can also affect how your brain processes information. As a result, you may experience impaired coordination, memory loss, and poor judgment. These effects can increase the likelihood of injuries and other negative outcomes.
Intoxication occurs when alcohol intake exceeds your body's ability to metabolise it. Your liver can metabolise about one ounce of alcohol per hour. On average, it takes about five and a half hours for your body to eliminate the amount of alcohol equivalent to the legal drinking limit from your bloodstream. However, alcohol can stay in your urine for up to 80 hours and in your hair follicles for up to three months.
Heavy or long-term drinking can lead to progressive changes in brain structure and function, increasing the risk of transitioning from controlled, occasional use to chronic misuse. Adolescent brains are particularly vulnerable to the negative effects of alcohol, and misuse during this stage can result in long-lasting changes in brain development. Additionally, prenatal alcohol exposure can cause brain damage, leading to a range of developmental, cognitive, and behavioural problems in children.
Alcohol misuse can also have detrimental effects on other parts of the body. It can lead to peripheral neuropathy, causing numbness in the arms and legs and painful burning in the feet. Alcohol-related nerve damage may also contribute to heart arrhythmias, hypotension, diarrhoea, and erectile dysfunction. Heavy drinking weakens the immune system, making it easier for diseases to take hold. It also impairs the pancreas's ability to produce digestive enzymes and regulate blood sugar levels, leading to conditions like pancreatitis, which can increase the risk of pancreatic cancer and diabetes.

Alcohol is a drug and can be toxic and addictive
Alcohol is a toxic substance with psychoactive properties and can be highly addictive. It is associated with a plethora of detrimental effects on society and public health. Alcohol use is linked to social harm, crime, and disorderly conduct in public spaces. It is also a leading cause of emergency room visits and contributes to a significant number of global deaths each year. The adverse effects of alcohol are most prominent when consumed in large quantities or with high frequency.
Alcohol affects a wide range of structures and processes within the central nervous system, causing neurocognitive impairment, dizziness, nausea, and vomiting. It also has toxic effects on the digestive and cardiovascular systems, increasing the risk of several types of cancer, liver disease, hepatitis, and cardiovascular disease. Alcohol is a known teratogen, increasing the risk of fetal alcohol spectrum disorders (FASDs) if consumed by women who are not using birth control.
Alcohol is often used as a form of self-medication by people with social anxiety disorder to overcome their inhibitions. However, prolonged and excessive self-medication with alcohol can worsen symptoms of anxiety and depression due to changes in brain chemistry. Alcohol can also intensify the effects of certain drugs, such as hypnotics and sedatives, and increase the risk of drug-induced toxicity when co-ingested with specific medications.
Reducing alcohol consumption or abstaining completely is the best way to lower the associated health risks. Official guidelines recommend that men and women drink no more than 14 units of alcohol per week, spread over several days with some alcohol-free days included. Binge drinking is particularly harmful to physical and mental health, and it is important to drink responsibly and within the recommended limits to minimize potential harm.

Alcohol has many uses outside of alcoholic drinks
Alcohol, in scientific terms, is a range of molecules formed when oxygen and hydrogen atoms bind with carbon atoms. Ethanol, a small molecule, is the specific alcohol found in alcoholic drinks.
Outside of alcoholic drinks, alcohol has many uses. Here are some examples:
Cooking and Food
Alcohol can be used in cooking and with food in various ways. Old red wine can be used as a meat tenderizer and marinade, adding a juicy, tender texture to cooked meat. Vanilla extract can be substituted with an equal amount of Frangelico or Bailey's Irish Cream. Beer can be used to trap and kill slugs and snails, which are attracted to the yeast in the beer.
Cleaning and Deodorizing
Alcohol can be used to kill odor-causing bacteria. For example, misting unflavored vodka can help get rid of musty odors. Similarly, pouring a small amount of vodka on one's feet can kill odor-causing bacteria. Alcohol can also be used to kill poison ivy. Mixing two tablespoons of vodka with two cups of water in a spray bottle can effectively kill poison ivy when sprayed on the leaves.
Other Uses
Alcohol can be used to jumpstart a dead car battery. Red wine is an acidic liquid that allows electrons to flow freely between the positive and negative terminals of the battery, providing enough energy to start the engine. Beer can also be added to the reservoir of a hose-end sprayer to water the lawn. The sugar in the beer stimulates microbes that help break up the soil, benefiting the lawn.
