The first step of the catabolic process is mediated by either MAO or COMT which depends on the tissue and location of catecholamines (for example degradation of catecholamines in the synaptic cleft is mediated by COMT because MAO is a mitochondrial enzyme). The next catabolic steps in the pathway involve 1181:
Catecholamines are secreted by cells in tissues of different systems of the human body, mostly by the nervous and the endocrine systems. The adrenal glands secrete certain catecholamines into the blood when the person is physically or mentally stressed and this is usually a healthy physiological

Catecholamine tests are done to identify rare tumors at the adrenal gland or in the nervous system. Catecholamine tests provide information relative to tumors such as: pheochromocytoma, paraganglioma, and neuroblastoma.

Dopamine is the first catecholamine synthesized from DOPA. In turn, norepinephrine and epinephrine are derived from further metabolic modification of dopamine. The enzyme dopamine hydroxylase requires copper as a
