  ChEBI: A hydrate that is the monohydrate form of glycine betaine.

• 일반 설명

  Betaine is a zwitterionic quaternary ammonium compound and is mainly present in animals, microorganisms and plants. It is one of the main constituent of several food items like wheat, shellfish, spinach and sugar beets. It is also termed as trimethylglycine, lycine, glycine betaine and oxyneurine. Betaine is a methyl derivative of glycine. It has a molecular mass of 117.2.

• Purification Methods

  Crystallise betaine from aqueous EtOH or EtOH/Et2O. The monohydrate loses H2O above 100o. Betaine undergoes internal alkylation to methyl dimethylaminoacetate Purification of Biochemicals — Amino Acids and Peptides above its melting point. It is also prepared by treating the hydrochloride (below) with silver oxide and recrystallising from EtOH/Et2O.
