Amino acid (Amino acid) as a molecular structure containing amino group (- NH2) and carboxyl (COOH) organic compounds. The formula is H2NRCOOH. Omega gamma delta beta alpha amino carbon atoms according to the connecting position in the carboxylic acid, can be divided into alpha, beta, gamma, Delta. Amino acids (C.C - C - C C - COOH).
Analysis of organic reagent is determined for inorganic elements in the separation and analysis of precipitant for enrichment, extraction agent, chelating agent and indicator for organic compounds, and not to refer to the general solvent, organic acid and organic alkali. These organic reagents must have good sensitivity and selectivity. With the development of analytical chemistry and the chemical industry, will be developed this kind of reagent sensitivity and better selectivity, such as since 1967 for some metal (such as alkali metal, alkaline earth metal) crown ether compounds and ammonium ion complexing is such.
