adenosin5monofoszfát

Adenosine-5'-monophosphate, often abbreviated as AMP, is a nucleotide composed of adenosine and a single phosphate group. Adenosine itself is a nucleoside made of adenine and ribose. AMP plays a fundamental role in cellular metabolism and is a building block for nucleic acids like RNA. It is also a precursor to adenosine diphosphate (ADP) and adenosine triphosphate (ATP), which are critical for energy transfer within cells. The energy currency of the cell, ATP, is generated through phosphorylation of ADP, which in turn is derived from AMP. AMP can also be synthesized from ADP through the enzyme adenylate kinase. In addition to its role in energy metabolism, AMP is involved in cellular signaling pathways. It can act as a signaling molecule, binding to specific receptors and triggering various cellular responses. The breakdown of ATP or ADP releases inorganic phosphate and generates AMP. This molecule is also a constituent of cyclic AMP (cAMP), an important secondary messenger in many signal transduction cascades.
