Exogenous ketone acid), β-HB acts like a ketone, providing the body with energy in the absence of glucose. In fact, β-Hydroxybutyrate is the most abundant ketone in the blood during ketosis. Acetone is an organic compound with the formula (CH3)2CO and is one of the simplest and smallest ketones. It is synthesized from the breakdown of acetoacetate in ketotic individuals within the liver. Ketone salts are natural compounds, such as β-HB, that are mixed with sodium, potassium, or calcium to improve absorption and overall bioavailability. Ketone esters are synthetic compounds that link an alcohol group to a ketone body, producing an ester.
Nitroethane give an oxazoline, which protonates to give a cationic surfactant. Like some other nitrated organic compounds, nitroethane is also used as a fuel additive and a precursor to explosives. Nitroethane is a useful solvent for polymers such as polystyrene and is particularly useful for dissolving cyanoacrylate adhesives. In niche applications, it has been used as a component in artificial nail remover and in overhead ceiling sealant sprays. Nitroethane has been used as a chemical feedstock in clandestine laboratories for synthesis of controlled substances such as amphetamines. Nitroethane is suspected to cause genetic damage and be harmful to the nervous system.
