Denatured alcohol, also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom, and as denatured rectified spirit, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. It is sometimes dyed so that ...
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Care should be taken with electrocautery, as ethanol is flammable. [1] Types of alcohol used include ethanol, denatured ethanol, 1-propanol, and isopropyl alcohol. [6] [7] Alcohols are effective against a range of microorganisms, though they do not inactivate spores. [7] Concentrations of 60% to 90% work best. [7]
Ethanol does not bind to plasma proteins or other biomolecules. [13] [2] [3] The rate of distribution depends on blood supply, [4] specifically the cross-sectional area of the local capillary bed and the blood flow per gram of tissue. [13] As such, ethanol rapidly affects the brain, liver, and kidneys, which have high blood flow. [2]
Alcohol inhalation is a method of administering alcohol directly into the respiratory system, with aid of a vaporizing or nebulizing device or bag. It is chiefly applied for recreational use, when it is also referred to as alcohol smoking, but it has medical applications for testing on laboratory rats, and treatment of pulmonary edema and viral pneumonia.
Ethanol precipitation usually by ice-cold ethanol or isopropanol. Since DNA is insoluble in these alcohols, it will aggregate together, giving a pellet upon centrifugation. Precipitation of DNA is improved by increasing ionic strength, usually by adding sodium acetate. Phenol–chloroform extraction in which phenol denatures proteins in the sample.
The amount of ethanol in the body is typically quantified by blood alcohol content (BAC); weight of ethanol per unit volume of blood. Small doses of ethanol, in general, are stimulant -like [ 58 ] and produce euphoria and relaxation; people experiencing these symptoms tend to become talkative and less inhibited, and may exhibit poor judgement.
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.
