The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Any measurement related to an enzyme, a protein that acts as a catalyst, increasing the rate at which a chemical reaction occurs without itself being destroyed or altered upon completion of the reaction, in the liver or in a sample of liver tissue. The liver is the large, dark-red organ located in the cranial portion of the abdomen of vertebrates, just behind or below the diaphragm, the functions of which include storage and filtration of blood; secretion of bile; detoxification of noxious substances; conversion of sugars into glycogen; synthesis and breakdown of fats and temporary storage of fatty acids; and synthesis of serum proteins.
