Enzymes Involved in the Biosynthesis and Degradation of Catecholamines

Abstract

Under normal physiological conditions, the concentration of tissue catecholamines does not change appreciably. This is because all the tissues that store and release catecholamines have the capacity to synthesize them. In addition, the sympathetic nerve endings and probably most of the central adrenergic structures have the property of taking up a considerable fraction of the catecholamines which have been released.
