Determination of an Electrochemical Series In electrochemistry‚ a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential which has a positive value. Voltaic cells have a variety of uses and you commonly refer to them as a “battery”. Half-cells are normally produced by placing a piece of metal into a solution containing a cation of the metal (e.g.‚ Cu metal in a solution

B) Site of synthesis: 1- In pancreas: Synthesis of taurine in the mammalian pancreas occurs through the cysteine sulfinic acid pathway. First‚ in this pathway is oxidation of cysteine sulfahydryl group to sulfonic acid‚ this oxidation is catalyzed by the enzyme cysteine dioxygenase. In turn‚ cysteine sulfonic acid is decarboxylated to hypotaurine by sulfonoalanine decarboxylase. It is not well known whether hypotaurine is then enzymatically or spontaneously oxidized to taurine. 2- in CNS: Biosynthesis
