Endogenous ketone bodies-
- Acetoacetic acid
- Beta-hydroxybutyrate
- Acetone
Other ketone bodies –
β-ketopentanoate and β-hydroxypentanoate
may be created as a result of the metabolism of synthetic triglycerides, such as triheptanoin
Triheptanoin –
Medication for the treatment of children and adults with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD)
“sweet & fruity” odor in breath of persons in ketosis or ketoacidosis is due to –
Acetone
Breath Smells – fruity or like nail polish remover
Acetone produced by ketogenesis – patients can have breath that smells fruity or like nail polish remover
