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 (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 ...
A barrel, often made of oak, used to age wine or distilled spirits. Alcohol Generally refers to ethanol, a chemical compound found in alcoholic beverages. It is also commonly used to refer to alcoholic beverages in general. Alcoholic fermentation The conversion by yeast of sugar into alcohol compounds Aldehyde
These may come in the form of oxygen free radicals, for example, which can change the chemical structures of compounds in beer that give them their taste. [22] Oxygen radicals can cause increased concentrations of aldehydes from the Strecker degradation reactions of amino acids in beer. [23]
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Glucose reacts with oxygen in the following reaction, C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O. Carbon dioxide and water are waste products, and the overall reaction is exothermic. The reaction of glucose with oxygen releasing energy in the form of molecules of ATP is therefore one of the most important biochemical pathways found in living organisms.
Carboys come in various volumes ranging from 4 to 25 L (1 to 7 US gal). The term carboy itself usually refers to a 5 US gal (19 L) carboy, unless otherwise noted. A 1 imp gal (4.5 L) carboy is sometimes called a jug. A 15 US gal (57 L) carboy is usually called a demijohn (in the Philippines, dama juana [10]).
Aliphatics compounds can be saturated, joined by single bonds (), or unsaturated, with double bonds or triple bonds ().If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound.
