Coronary vasomotion disorders represent frequent functional causes of angina in patients with unobstructed coronaries. The underlying mechanism of angina (endotype) in these patients can be determined by a comprehensive invasive diagnostic procedure based on acetylcholine provocation testing followed by Doppler-derived assessment of the coronary flow reserve and microvascular resistance.

Hydrolysis of ATP

2019
The bonds of adenosine triphosphate (ATP) can be broken through the addition of water, releasing one or two phosphate groups in an exergonic process called hydrolysis. This reaction liberates the energy in the bonds for use in the cell—for instance, to synthesize proteins from amino acids. If one phosphate group is removed, a molecule of ADP—adenosine diphosphate—remains, along with inorganic phosphate. ADP can be further hydrolyzed to AMP—adenosine monophosphate—by the removal of a second...

Adenylate kinase links the cellular pools of ATP, ADP, and AMP through an interconversion reaction. When ATP-consuming reactions reduce available ATP, this reaction can contribute to changes in AMP levels. Consequently, AMP reflects shifts in the balance of adenine nucleotides rather than acting as an isolated metabolite, helping connect energy use with downstream regulation.
Rising AMP activates AMP-activated protein kinase, or AMPK, when cellular energy conditions become less favorable. AMPK then promotes pathways that help restore energy while limiting processes that consume substantial energy. This response makes AMP an important metabolic signal because it links the immediate state of adenine nucleotides to broader cellular adjustments.
AMP levels change when ATP-consuming reactions reduce the ATP pool, so they provide a biochemical indication that energy demand has affected the cell. Interpreting AMP together with ATP and ADP can therefore connect nucleotide changes with energy regulation. This relationship is useful for explaining how cells detect and respond to altered energetic conditions.
ATP availability describes the nucleotide directly consumed by many cellular reactions, whereas AMP contributes to signaling when ATP use changes the adenine-nucleotide balance. The increase in AMP can activate AMPK, which coordinates energy-restoring and energy-limiting responses. Thus, AMP provides regulatory information about energy stress in addition to reflecting nucleotide metabolism.
Studying AMP can reveal how cells coordinate metabolic regulation with changing energy demands. Its relationship to ATP-consuming reactions and AMPK activation helps researchers examine pathways that restore energy, restrict energy-intensive activities, and respond to altered cellular conditions. These observations provide context for understanding energy control across biological systems.
Exercise responses can be examined through AMP because increased cellular energy demand may affect ATP availability and the resulting adenine-nucleotide state. AMP-associated AMPK signaling offers a way to study how cells promote energy-restoring pathways while limiting energy-intensive processes. This connects nucleotide metabolism with the cellular adjustments associated with exercise.
AMP research helps connect cellular energy status with signaling networks involved in nutrient sensing, growth, and survival. Changes in AMP can engage AMPK, which adjusts energy-related pathways and may influence how cells respond when resources or energy conditions change. This makes AMP useful for placing metabolic regulation within broader biological signaling networks.
