[94], Alcohol is fully legal and available in most countries of the world. These include Collins reagent and Dess-Martin periodinane. [88] Acetone (propanone) is a ketone rather than an alcohol, and is reported to produce similar toxic effects; it can be extremely damaging to the cornea.[88]. [7] People who have fasted overnight have been found to reach peak ethanol concentrations more rapidly, at within 30 minutes of ingestion. News 45(43):73. [74][75] One of ethanol's primary effects is the allosteric inhibition of NMDA receptors and facilitation of GABAA receptors (e.g., enhanced GABAA receptor-mediated chloride flux through allosteric regulation of the receptor). In chemistry, alcohol is an organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. The latter can also be thought of as an ethyl group linked to a hydroxyl (alcohol) group and can be abbreviated as EtOH. These cells are then replaced with scar tissue, leading to the condition called cirrhosis. isobutylene from tert-butyl alcohol. Flagyl® IV and Flagyl® I.V. Compendium of pharmaceuticals and specialties, Ottawa: Canadian Pharmacists Association. Some low molecular weight alcohols of industrial importance are produced by the addition of water to alkenes. Methanol and ethanol are less acutely toxic. Montvale, NJ: Medical Economics Company Inc; 1998:2563-5. [2] 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 beverages. In the Ziegler process, linear alcohols are produced from ethylene and triethylaluminium followed by oxidation and hydrolysis. [27] In 2002, it was estimated that 1 million violent crimes in the United States were related to alcohol use. Alcohol was originally used for the very fine powder produced by the sublimation of the natural mineral stibnite to form antimony trisulfide Sb 2S 3. [15], IUPAC nomenclature is used in scientific publications and where precise identification of the substance is important, especially in cases where the relative complexity of the molecule does not make such a systematic name unwieldy. It is one of the oldest and most common recreational substances, causing the characteristic effects of alcohol intoxication ("drunkenness"). When applied to a terminal alkene, as is common, one typically obtains a linear alcohol:[22]. [19][20][21][60] Ethanol has specifically been found in functional assays to enhance or inhibit the activity of a variety of ion channels, including the GABAA receptor, the ionotropic glutamate AMPA, kainate, and NMDA receptors, the glycine receptor,[62] the nicotinic acetylcholine receptors,[63] the serotonin 5-HT3 receptor, voltage-gated calcium channels, and BK channels, among others. The direct oxidation of primary alcohols to carboxylic acids can be carried out using potassium permanganate or the Jones reagent. [81][82] In the upper range of recreational ethanol concentrations of 20 to 50 mM, depression of the central nervous system is more marked, with effects including complete drunkenness, profound sedation, amnesia, emesis, hypnosis, and eventually unconsciousness. Alcohol causes a plethora of detrimental effects in society, both to the individual and to others. Primary alkyl halides react with aqueous NaOH or KOH mainly to primary alcohols in nucleophilic aliphatic substitution. Alcohol has a variety of short-term and long-term adverse effects. Consequently, LPS levels increase in the portal vein, liver and systemic circulation after alcohol intake. When treated with acid, these alcohols lose water to give stable carbocations, which are commercial dyes.[32]. [11] Al- is the Arabic definite article, equivalent to the in English. [73], Ethanol's rewarding and reinforcing (i.e., addictive) properties are mediated through its effects on dopamine neurons in the mesolimbic reward pathway, which connects the ventral tegmental area to the nucleus accumbens (NAcc). [95] However, laws banning alcohol are found in the Middle East and some Indian states as well as some Native American reservations in the United States. Cetyl alcohol is present in a waxy white powder or flake form at room temperature, and is insoluble in water and soluble in alcohols and oils. Butanol, with a four-carbon chain, is moderately soluble. Tertiary alcohols (R1R2R3C-OH) are resistant to oxidation. The reason is that alcohol and metronidazole can lead to side effects such as flushing, headache, nausea, vomiting, abdominal cramps, and sweating. For instance, (CH3)3COH can be named trimethylcarbinol. Other plants, such as the cactus or sugar cane may be used in liquor production. [16] When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH3CH2CH2OH, propan-2-ol for CH3CH(OH)CH3. Saccharomyces yeast are known to produce these higher alcohols at temperatures above 75 °F (24 °C). [95] In addition, besides are several regulations on alcohol sales and use in many countries throughout the world. Because alcohol stimulates a person's stomach to secrete acid, a person with PUD should avoid drinking alcohol on an empty stomach.
