Formaldehyde

Formaldehyde is the most simple aldehyde (a carbon with a double bonded O and at least one bond to H). It is also known as Methanal. It was first reported in 1859 by a Russian chemist, Aleksandr Butlerov, and has been used in multiple commercial industries. In the chemistry business, formaldehyde is used as a building block for larger substances (known as a precursor). In the textiles industry, it is used to finish clothes and make them crease resistant.

Formaldehyde cross-links amino groups, making them resistant to oxidation and breakdown by microbes. This makes it a fantastic preservation agent, and has been historically used in embalming of biological compounds.

Unfortunately, this cross-linking of amino acids is very dangerous to living organisms, and has described by the US National Toxicology Program to be "known to be a human carcinogen".[14][15][16]

Formaldehyde is produced by the following enzymatic reaction of Methanol:

2 CH3OH + O2 → 2 CH2O + 2 H2O

Our livers will metabolize Methanol into Formaldehyde, which then becomes Formic Acid. Formic acid causes a ton of problems with mitochondria, and formic acid build-up is associated with blindness. When people accidentally ingest Methanol, they may experience symptoms such as blindness. During US prohibition, many black market Ethanol dealers (Ethanol is the alcohol in wine/beer/liquor) would spike their product with cheap Methanol. This caused lots of health problems for people trying to get their alcohol fix illegally, and was a contributing factor to the cessation of prohibition.

Formaldehyde is also formed in trace amounts from the combustion of Methane, so try not to huff the bunsen burner fumes or you might experience mild symptoms!
