CLINICAL MEASUREMENT - ANNOTATIONS

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.

Term:	logarithm of the concentration of acetylcholine at which the reduction in force during dilation of a blood vessel is half the maximum value (Log EC50)	go back to main search page
Accession:	CMO:0000725	browse the term
Definition:	A calculated value for logarithm of the concentration of acetylcholine (ACh), the ester of acetic acid and choline with chemical formula CH3C=OO(CH2)2-N(+)-(CH3)3 and IUPAC name 2-acetoxy-N,N,N-trimethylethanaminium, which acts as a neurotransmitter, at which the dilation of a blood vessel in response to the application of ACh is half maximal. The logarithm of the concentration is the exponent indicating the power to which 10 must be raised to obtain that concentration value.
Synonyms:	exact_synonym:	acetylcholine Log half maximal effective concentration (Log EC50)
	xref:	CHEBI:15355
