Catecholamines
catecholamines
Manufactured chiefly by the chromaffin cells of the adrenal glands, these hormones are involved in readying the body for the "fight-or-flight" response (also known as the alarm reaction).
The three catecholamines are dopamine, norepinephrine, and epinephrine. They are neurotransmitters and hormones that play key roles in the body's stress response and regulation of mood, attention, and arousal.
adrenal corticotropic hormone (ACTH), calcitonin, catecholamines, gastrin, human chorionic gonadogropin (hCG), and prolactin
Steroid hormones are not stored in the secretory cell after being synthesized. Instead, they are synthesized on demand from cholesterol and released immediately into the bloodstream.
It is an amine attached to a catechol group thus the name catecholamine, they are naturally occurring hormones and nerotransmitters such as: dopamine, epinephrine & nor-epinephrine.

Catecholamines are soluble in water.
Catecholamines (such as dopamine, norepinephrine, epinephrine) have a catechol ring structure, while non-catecholamines do not. Catecholamines are synthesized from the amino acid tyrosine and are involved in the fight-or-flight response, whereas non-catecholamines (such as serotonin, histamine) have different functions in the body.

Cortisol and epinephrine. These includes basically: 1. Glucocorticoids- examples are cortisol, corticosterones etc 2. Mineralocrticoids- examples are catecholamines (epinephrine and norepinephrines).
