Metabolite Identification
Common NameNormetanephrine
DescriptionNormetanephrine, also known as normetadrenaline or N111, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. Normetanephrine is a solid that is soluble in water. Normetanephrine is a metabolite of norepinephrine created by action of catechol-O-methyl transferase on norepinephrine. Within humans, normetanephrine participates in a number of enzymatic reactions. In particular, normetanephrine can be converted into 3-methoxy-4-hydroxyphenylglycolaldehyde through its interaction with the enzyme amine oxidase [flavin-containing] A. It is also involved in the metabolic disorder called transient tyrosinemia of the newborn. This compound is excreted in the urine and is found in certain tissues. It is a marker for catecholamine-secreting tumors such as pheochromocytoma (PMID: 30538672 ).
