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.

Alcohol dehydrogenase instead enzymatically converts ethanol to acetaldehyde, a less toxic organic molecule. [ 15 ] [ 20 ] Additional treatment may include sodium bicarbonate for metabolic acidosis, and hemodialysis or hemodiafiltration to remove methanol and formate from the blood. [ 15 ]
Methanol is used as a denaturant for ethanol, the product being known as denatured alcohol or methylated spirit. This was commonly used during the US prohibition to discourage consumption of bootlegged liquor, and ended up causing several deaths. [49] It is sometimes used as a fuel in alcohol lamps, portable fire pits and camping stoves.
Some research suggests that part of the way alcohol use may reduce the risk of heart attacks is the impacts it has on the limbic system, such as limiting stress signals in the brain.
Doctors generally agree that a little alcohol is OK — and a lot is bad. “If someone is not a current drinker, I would not recommend starting to drink alcohol just for the potential health ...
The addition of methanol, which is poisonous, renders denatured alcohol unfit for consumption, as ingesting denatured alcohol may result in serious injury or death. [2] Thus denatured alcohol is not subject to the taxes usually levied on the production and sale of alcoholic beverages. Aniline was used to denature colza oil in the 1980s. [3]
Alcohol-related deaths have climbed nationally in the past few years: The U.S. saw a 25% spike in deaths during the first year of the pandemic, a trend that particularly affected middle-aged adults.
