Betaine, e mohiotia ana ko glycine trimethyl te tote o roto, he puhui taiao kore-paitini me te kino kore, quaternary amine alkaloid. He ma, he rau rite te karaihe me te tauira rāpoi c5h12no2, te taumaha rāpoi 118 me te rewa o te 293 ℃. He reka, he matū rite tonu ki te huaora. He kaha te pupuri makuku me te ngawari ki te tango i te makuku me te deliquesce i te pāmahana rūma. Ko te momo hydrated he wairewa i roto i te wai, te mewaro me te waihano, me te paku whakarewa ki te etera. He kaha te hanganga matū o te Betaine, ka taea e ia te tu atu i te pāmahana teitei o te 200 ℃, he kaha te ātete hāoratanga. Kua whakaatuhia e nga rangahau terabetaineKa taea e koe te whakakapi i te methionine i roto i te whakawhitinga kararehe.

BetaineKa taea te whakakapi katoa i te methionine i roto i te tuku methyl. I tetahi taha, ka whakamahia te methionine hei taputapu ki te hanga i nga pūmua, a, i tetahi atu ringa, ka uru ki te methyl metabolism hei kaituku methyl.BetaineKa taea e ia te whakatairanga i te mahi o te betaine homocysteine ​​​​methyltransferase i roto i te ate me te whakarato i te methyl kaha tahi, kia taea ai te methylated methionine demethylation hua homocysteine ​​ki te hanga methionine mai i te wahanga, kia rite ki te tuku tonu i te methyl mo te tinana me te iti o te methionine hei kawe me te betaine hei puna methyl, Na, ko te nuinga o te methionine ka whakamahia hei whakaora i te mana methionine. Ka noho tahi, ka whakahekehia te betaine i muri i te methylated hei whakaputa i te serine me te glycine, katahi ka piki ake te kukū o nga waikawa amino i roto i te toto (kamoun, 1986).

I whakanuia e Betaine nga ihirangi o te methionine, te serine me te glycine i roto i te serum. Puchala et al. He rite nga paanga whakamatautau ki nga hipi. Ka taea e Betaine te taapiri i nga waikawa amino penei i te arginine, methionine, leucine me te glycine i roto i te serum me te tapeke o nga waikawa amino i roto i te serum, katahi ka pa ki te whakakorenga o te auxin;Betaineka whakatairanga i te huringa o te waikawa aspartic ki te waikawa n-methylaspartic (NMA) na roto i te kaha o te methyl metabolism, a ka taea e te NMA te pa ki te hanganga me te whakakorenga o te auxin i roto i te hypothalamus, katahi ka te taumata o te auxin i roto i te tinana.
