Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Ethanol is also known chemically as alcohol, ethyl alcohol, or drinking alcohol. It is a simple alcohol with a molecular formula of C 2 H 6 O and a molecular weight of 46.0684 g/mol. The molecular formula of ethanol may also be written as CH 3 −CH 2 −OH or as C 2 H 5 −OH.
Alcoholism, also known as "alcohol use disorder", is a broad term for any drinking of alcohol that results in problems. [45] Alcoholism reduces a person's life expectancy by around ten years [46] and alcohol use is the third-leading cause of early death in the United States. [43] Consumption of alcohol in any quantity can cause cancer.
In the United States, proof represents twice the alcohol content as a percentage of volume. Thus, a 100 proof beverage is 50% alcohol by volume and a 150 proof beverage is 75% alcohol. In the Imperial system, proof, (or 100% proof), equals 57.06% ethanol by volume, or 48.24% by weight. Absolute or pure ethanol is 75.25 over proof, or 175.25 proof.
A tincture is typically an extract of plant or animal material dissolved in ethanol (ethyl alcohol). Solvent concentrations of 25–60% are common, but may run as high as 90%. [78] In chemistry, a tincture is a solution that has ethanol as its solvent.
Exposure to ethanol is known to promote further induction of this enzyme in fetal and adult tissues. CYP2E1 is a major contributor to the so-called Microsomal Ethanol Oxidizing System (MEOS) [111] and its activity in fetal tissues is thought to contribute significantly to the toxicity of maternal ethanol consumption.
Ethanol (grain alcohol) is a widely used and abused psychoactive drug. If ingested, the so-called "toxic alcohols" (other than ethanol) such as methanol, 1-propanol, and ethylene glycol metabolize into toxic aldehydes and acids, which cause potentially fatal metabolic acidosis. [30]
