A catecholamine (CA) is a monoamine, an organic compound that has a catechol (benzene with two hydroxyl side groups) and a side-chain amine. Catechol is a chemical, but a catechol may also be used as the name of a substituent, where it represents a 1,2-dihydroxybenzene group.Catecholamines are derived from the amino acid tyrosine. Catecholamines are water-soluble and are 50%-bound to plasma proteins in circulation.Included among catecholamines are: epinephrine (adrenaline), norepinephrine (noradrenaline) and dopamine; all of which are produced from phenylalanine and tyrosine.Release of the hormones epinephrine and norepinephrine from the adrenal medulla of the adrenal glands is part of the fight-or-flight response.xtremely high levels of catecholamine can also be caused by neuroendocrine tumors in the adrenal medulla, a treatable condition known as pheochromocytoma. High levels of catecholamines can also be caused by monoamine oxidase A (MAO-A) deficiency.

There are two types of tyrosine derived hormones: thyroid hormone and catecholamines. Thyroid hormone is one of the most important in the body because it regulates the development of organs and metabolism. Norepinephrine and epinephrine are catecholamines. Both are stress hormones and are also neurotransmitters.ther examples include LH (lutenizing hormone) and FSH (follicle stimulating hormone). LH acts on the gonads to produce eggs and sperm while FSH stimulates the gonads to produce steroids. Non-tropic hormones behave in an opposite manner.

Amino Acid Derivatives. There are two groups of hormones derived from the amino acid tyrosine: 1  Thyroid hormones are basically a double tyrosine with the critical incorporation of 3 or 4 iodine atoms.2  Catecholamines include epinephrine and norepinephrine, which are used as both hormones and neurotransmitters.mino Acid Derivatives.

Catecholamines testing may be used in follow up to plasma free metanephrines and/or urine metanephrines testing to help confirm or rule out rare tumors called pheochromocytomas and paragangliomas in symptomatic people. It also may be ordered when a tumor is treated or removed to monitor for recurrence.rine catecholamines testing measures the total amount of catecholamines released into the urine in 24 hours. Since the hormone levels may fluctuate significantly during this period, the urine test may detect excess episodic production that is missed with the blood test.

Under this method of classification, there are four groupings: steroids, peptides, amino acid and fatty acid. Steroid hormones are derived from cholesterol. The sex hormones (androgens, estrogens and progesterone) and hormones produced in the adrenal glands.Adrenal gland hormones include the mineralcoritcosteriods and gluccorticosteriods. Steroid hormones have a few important functions in the body including water balance, sexual development and stress response.Steroid Hormone Production from Cholesterol. The next type is the amino acid derivative hormones.ther examples include LH (lutenizing hormone) and FSH (follicle stimulating hormone). LH acts on the gonads to produce eggs and sperm while FSH stimulates the gonads to produce steroids. Non-tropic hormones behave in an opposite manner.

An adrenergic storm is a sudden and dramatic increase in serum levels of the catecholamines adrenalin and noradrenalin (also known as epinephrine and norepinephrine respectively), with a less significant increase in dopamine transmission. subarachnoid hemorrhage can also cause an adrenergic storm, and catecholamine storm is part of the normal course of Rabies infection, and is responsible for the severe feelings of agitation, terror, and dysautonomia present in the pre-coma stage of the disease.

Extremely high levels of catecholamine can also be caused by neuroendocrine tumors in the adrenal medulla, a treatable condition known as pheochromocytoma.

A small but relatively constant fraction of the circulating levels of epinephrine and norepinephrine in the blood is excreted into the urine (Frankenhaeuser, 1971; Levi, 1972). Consequently, assessment can be made using blood (usually plasma) as well as urine.ong-lasting elevated catecholamine levels are thought to contribute to the development of atherosclerosis and to predispose to myocardial ischemia (Karasek et al., 1982; Krantz & Manuck, 1984; Rozanski et al., 1988; Yusuf et a., 2004).
