Adenosine Adenosine is an endogenous agonist of the ghrelin/growth hormone secretagogue receptor. However, while it is able to increase appetite, unlike other agonists of this receptor, adenosine is unable to induce the secretion of growth hormone and increase its plasma levels.

amp 1 Short for adenosine monophosphate. An organic compound that is composed of adenosine and one phosphate group. It is one of the nucleotides present in DNA and RNA, and is also the fundamental component of ATP and ADP. During certain cellular metabolic processes, AMP forms from ADP when the latter loses a phosphate group, and AMP forms ADP by acquiring a phosphate group.

Adenosine This is a particularly important mechanism for matching coronary blood flow to the metabolic needs of the heart. In coronary vascular smooth muscle, adenosine binds to adenosine type 2A (A 2A) receptors, which are coupled to the Gs-protein. Activation of this G-protein stimulates adenylyl cyclase (AC in figure), increases cAMP and causes protein kinase activation.

Positive and Negative externalities An externality is defined as a benefit or cost that is imposed on a third party, such as society, other than the producer or consumer of a good or service, or, more simply, an economic side effect. The more of a product that is consumed or produced, the more of an externality that results.

Adenine Adenine is one of the two purine nucleobases (the other being guanine) used in forming nucleotides of the nucleic acids. In DNA, adenine binds to thymine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. In RNA, which is used for protein synthesis, adenine binds to uracil.

The Medical Minute: Stress tests - echo vs. nuclear In these, the heart can be stressed using adenosine or dobutamine. These pharmacologic stress tests are always coupled with an imaging modality because their effects may not be detectable with an EKG alone. Adenosine is a potent agent that dilates the blood vessels and increases blood flow.

- Adenylyl Cyclase. Adenylyl cyclase is the enzyme that synthesizes cyclic adenosine monophosphate or cyclic AMP from adenosine triphosphate (ATP). Cyclic AMP functions as a  second messenger  to relay extracellular signals to intracellular effectors, particularly protein kinase A.his form of the enzyme appears to be activated by bicarbonate ion. When adenylyl cyclase is activated, it catalyses the conversion of ATP to cyclic AMP, which leads to an increase in intracellular levels of cyclic AMP.
