Ketone bodies are two molecules, acetoacetate and b-hydroxybutyrate. The term. âketone bodyâ is historical: only acetoacetate is an actual ketone.

The brain generally uses 60-70% of total body glucose requirements, and. always requires some glucose for normal functioning.
Definition: A keytone is a compound containing a carbonyl functional group bridging two groups of atoms. The general formula for a ketone is RC(=O)R' where R and R' are alkyl or aryl groups. IUPAC ketone functional group names contain oxo or keto.Ketones are named by changing the-e on the end of the parent alkane name to-one. Examples: Acetone is a ketone. The carbonyl group is connected to the alkane propane, therefore the IUPAC name for acetone would be propanone.UPAC ketone functional group names contain oxo or keto. Ketones are named by changing the-e on the end of the parent alkane name to-one. Examples: Acetone is a ketone.
