Betaine, also known as betaine, trimethylammonium betaine, is a quaternary ammonium derivative of glycine, and is a type of nitrogen methyl compound or trimethyl formed after the hydrogen on the amino acid amino group is replaced by a methyl group. Inner salt. Common are glycyl betaine, beta-alanyl betaine and prolyl betaine. Prismatic crystals or leaf-like crystals are obtained from ethanol, with sweet taste and easy deliquescence. Melting point is 293ºC, decomposes at 300ºC, soluble in water and ethanol, insoluble in ether, can be isomerized to methyl dimethylaminoacetate at the melting point, from free acid HO-N(CH3)3-CH2COOH The crystal of its monohydrate is obtained in aqueous solution, it loses water at 100 ºC to form betaine, which is stable in acid. With concentrated aqueous solution Maillard reaction with sugar (browning reaction). It exists in plants such as beetroot and cottonseed, and is also contained in animal substances such as thorny shark meat and crab juice. It can be recovered from beet sugar mother liquor. It can also be obtained by methylation of aminoacetic acid or by the action of chloroacetic acid
