Most of the 140 types of molecules found in space have been discovered here, including some common on Earth: acetic acid (vinegar), ethylene glycol (the chief ingredient in antifreeze), and a basic sugar known as
glycol aldehyde.
If ingested, the so called toxic alcohols (other than ethanol) such as methanol, propanol, and ethylene
glycol metabolize into toxic
aldehydes and acids, which cause potentially fatal metabolic acidosis.
