obsolete cellular ketone body metabolic process https://github.com/geneontology/go-ontology/issues/29021 true Reactome:R-HSA-74182 The reason for obsoletion is that this term is redundant to GO:1902224, ketone body metabolic process OBSOLETE. The chemical reactions and pathways involving ketone bodies, any one of the three substances: acetoacetate, D-3-hydroxybutyrate (beta-hydroxybutyrate) or acetone, as carried out by individual cells. Although 3-hydroxybutyrate is not a ketone, it is classed as a ketone body because it exists in an equilibrium with acetoacetate. Ketone bodies may accumulate in excessive amounts in the body in starvation, diabetes mellitus or in other defects of carbohydrate metabolism. biological_process GO:0046950 cellular ketone body metabolism ketone body metabolic process
