EPINEPHRINE BIOSYNTHETIC PATHWAY (PW:0000803)

View Ontology Report

Description

The synthesis and release of catecholamines dopamine, norepinephrine and epinephrine are triggered by various but distinct conditions and stresses. Norepinephrine and epinephrine, also known as noradrenaline and adrenaline, act as neurotransmitters and hormones. They signal via various adrenergic receptors, G protein-coupled receptors (GPCR) which couple to distinct G alpha subunits of heterotrimeric G proteins. Stresses such as cold and pain prompt the synthesis of norepinpehrine in sympathetic
