ketoonidest
Ketoonidest is a term that appears to be a misspelling or a non-standard term. It is possible the user is referring to "ketones" or perhaps a specific brand name or compound that is not widely recognized in scientific literature or common parlance.
If the intended term is "ketones," these are organic compounds characterized by the presence of a carbonyl
If "ketoonidest" refers to a different concept, further clarification would be necessary to provide accurate information.
