Adenosin-5-triphosphate disodium salt (ATP), 5 g

Discovered in 1929 by Karl Lohmann. Main molecular currency of energy in all cells and highly important regulator of energy providing processes. During hydrolysis of phospho-anhydride bonds, energy of 30.5 kJ/mol (ADP) or 45.6 kJ/Mol (AMP), respectively, is released. Ligand of purinergic receptors and intercellular signalling molecule. Additionally, ATP is coenzyme of phosphate-transferring kinases like proteine kinases A, proteine kinases C, calmodulin-dependent kinases, and substrate of adenylate cyclases, which synthesize the second-messenger molecule cAMP.
