Betaine, makwaara dị ka glycine trimethyl esịtidem nnu, bụ ihe na-adịghị egbu egbu na-adịghị emerụ eke compound, quaternary amine alkaloid.Ọ bụ prismatic na-acha ọcha ma ọ bụ akwụkwọ dị ka kristal nwere usoro ihe omimi c5h12no2, ịdị arọ molecular nke 118 na ebe agbaze nke 293 ℃.Ọ na-atọ ụtọ ma bụrụ ihe yiri vitamin.Ọ nwere njigide mmiri siri ike yana ọ dị mfe ịmịkọrọ mmiri na mmiri na-ekpo ọkụ n'ime ụlọ okpomọkụ.Ụdị hydrated na-agbaze na mmiri, methanol na ethanol, na ntakịrị soluble na ether.Betaine nwere usoro kemịkalụ siri ike, nwere ike iguzogide oke okpomọkụ nke 200 ℃ ma nwee nguzogide oxidation siri ike.Nnyocha egosiwo nabetainnwere ike dochie methionine nke ọma na metabolism anụmanụ.

Betainenwere ike dochie methionine kpamkpam na ntinye nke methyl.N'otu aka ahụ, a na-eji methionine mee ihe dị ka ihe na-emepụta protein, na n'aka nke ọzọ, ọ na-ekere òkè na methyl metabolism dị ka onye na-enye onyinye methyl.Betainenwere ike ịkwalite ọrụ betaine homocysteine ​​​​methyltransferase n'ime imeju ma na-enye methyl na-arụ ọrụ ọnụ, nke mere na methionine demethylation ngwaahịa homocysteine ​​​​nwere ike ịbụ methylated ka ọ bụrụ methionine site na ọkọ, ka ọ na-aga n'ihu na-enye methyl maka metabolism ahụ na obere methionine dị ka onye na-ebu ya. na betaine dị ka isi iyi methyl, Mgbe ahụ, a na-eji ọtụtụ methionine eme protein, nke nwere ike ịchekwa methionine ma jiri ike mee ihe.Ọnụ, a na-eweda betaine ọzọ ka emechara ya methylated wee mepụta serine na glycine, wee mụbaa mkpokọta amino acid n'ime ọbara (kamoun, 1986).

Betaine mụbara ọdịnaya nke methionine, serine na glycine n'ime ọbara.Puchala et al.Nwere mmetụta nnwale yiri nke ahụ na atụrụ.Betaine nwere ike tinye amino asịd dị ka arginine, methionine, leucine na glycine n'ime ọbara yana mkpokọta amino acid dị na serum, wee metụta nsị auxin;Betainenwere ike kwalite ntughari nke aspartic acid na n-methylaspartic acid (NMA) site na methyl metabolism ike, na NMA nwere ike imetụta nhazi na excretion nke auxin na hypothalamus, na mgbe ahụ ọkwa nke auxin n'ime ahụ.
