Betaine is also known as trimethylamine ethanolactone\Betulin\glycine betaine ,Quaternary ammonium derivative of glycine,It is a kind of nitrogen methyl compound or trimethyl internal salt formed after the hydrogen on the amino acid is replaced by a methyl group.
Common glycyl betaine,b-Alanyl betaine and prolyl betaine.fromethanolPrismatic crystal or blade crystal in,Sweet,Deliquescent.melting point293℃,300At ℃decomposition,Soluble in water\methanolandethanol,Insoluble in ether,Can isomerize to methyl dimethylaminoacetate at melting point,From free acidHO-N(CH3)3-CH2COOHCrystals of its monohydrate were obtained from aqueous solution of,It is in100Betaine is produced by water loss at ℃,Stable in acid.With concentrated potassium hydroxide aqueous solutionTrimethylamine.
Maillard reaction with sugar(Browning reaction).Found in plants such as beet roots and Cottonseeds,It is also contained in animal substances such as the flesh of barbed shark and the juice of crab.It can be recovered from sugar beet mother liquor.It can also be caused by the methylation of aminoacetic acid or by the interaction of chloroacetic acid withTrimethylamineFormed by action.Clinically, it is similar toN-Amidine glycineshare,myasthenia gravis ,Analytical chemistry is also used as a reagent to identify gold.This product is betaine amphoteric surfactant,Used as leveling agent for vat dyeing.In drought or salt stress,Many plants accumulate betaine,Become the main organic solute for osmoregulation,It has a protective effect on proteins and cell membranes.
