Бетаин моногидра

Описание

Betaine monohydrate is a minor pathway of methionine biosynthesis as an end product of oxidative choline metabolism. Betaine inner salt monohydrate is a variant of betaine. This chemical is known for its ability to function as an osmolyte, meaning it helps maintain cell volume and fluid balance within cells by controlling water flow in and out. This property is in various biological processes, especially in plants and microorganisms, to withstand stress from environmental changes, such as salinity or dehydration. In industrial applications, betaine inner salt monohydrate is utilized for its compatibility with a wide range of formulations, contributing to the stability and functionality of products. The mixture of betaine monohydrate and glycerol can form a Deep eutectic solvent (DES) at a molar ratio 1:2. Betaine monohydrate-glycerol DES can extract palmitic acid in palm oil.

Определение

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

Общее описание

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.

Методы очистки

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.
