Norepinephrine metabolites

In mammals norepinephrine (aka noradrenaline) is rapidly degraded to various metabolites. The principle metabolites are:


 * Normetanephrine (via the enzyme catechol-O-methyl transferase, COMT)
 * 3,4-Dihydroxymandelic acid (via monoamine oxidase, MAO)
 * 3-Methoxy-4-hydroxymandelic acid (via MAO)
 * 3-Methoxy-4-hydroxyphenylglycol (via MAO)
