Catecholamines

The term catecholamine comes from the aromatic dialcohol, catechol. The most common catecholamines are epinephrine, norepinephrine, dopamine, and dihydroxyphenylalanine (L-Dopa).

Catecholamine analogs, such as mescaline and amphetamine have potent psychopharmacological properties.

Figure 21.32 depicts the pathway to catecholamines from tyrosine.
