Etymology
Catecholamine is made of catechol, a name for a small chemical ring first found in a plant dye, and amine, which means 'related to ammonia' and is like 'amino' in 'amino acid'. So catecholamines are nitrogen-containing chemicals such as adrenaline and norepinephrine that the body sends out quickly as hormones or messengers in stress.
