Definitions

Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.Amino acids can be classified according to the locations of the core structural functional groups, as alpha- (α-), beta- (β-), gamma- (γ-) or delta- (δ-) amino acids; other categories relate to polarity, ionization, and side chain group type (aliphatic, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acid residues form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life on Earth and its emergence.

Polarographic refers to a method or technique used in analytical chemistry to detect and measure the presence and concentration of various substances in a solution. It involves measuring the current that passes through a solution as a function of an applied voltage to monitor chemical reactions, especially reductions and oxidifications. This technique is typically carried out using a polarographic cell with a dropping mercury electrode or other types of electrodes. The term polarographic is typically associated with the pioneering work of Czech chemist Jaroslav Heyrovský, who was awarded the Nobel Prize in 1959 for developing this method.
