Adrenergic Receptors and their distribution

by

Introduction Adrenergic receptors are the glycoproteins present on cell surface which recognize and selectively binds to the catecholamines (norepinephrine, epinephrine, etc). These receptors are the mediators of sympathetic nervous system like smooth muscle contraction, cardiac contraction, etc. Adrenergic receptors produce its action by transducing external catecholamine stimulus into the intracellular signal. Activation or blockage of … Read more

Biosynthesis of catecholamine and Their Catabolism

by

Introduction Catecholamines are the neurotransmitters containing catechol ring with two hydroxyl side groups in their structure. The biosynthesis of catecholamines constitutes a fascinating and intricate processes in human body. Catecholamines including dopamine, norepinephrine, epinephrine are essential neurotransmitter involved in mood regulation, stress response and cardiovascular function. Understanding the biosynthesis of catecholamines is crucial for unravelling … Read more
