Betaine, eo hape e tsejoang e le glycine trimethyl letsoai la ka hare, ke motsoako oa tlhaho o se nang chefo le o se nang kotsi, quaternary amine alkaloid. Ke prismatic e tšoeu kapa lekhasi le kang kristale le foromo ea molek'hule c5h12no2, boima ba molek'hule ke 118 le ntlha e qhibilihang ea 293 ℃. E na le tatso e monate 'me ke ntho e tšoanang le livithamine. E na le ho boloka mongobo o matla 'me ho bonolo ho monya mongobo le li-deliquesce mocheso oa kamore. Mofuta oa hydrated o qhibiliha ka metsing, methanol le ethanol, 'me o qhibiliha hanyenyane ho ether. Betaine e na le sebopeho se matla sa lik'hemik'hale, e khona ho mamella mocheso o phahameng oa 200 ℃ mme e na le khanyetso e matla ea oxidation. Liphuputso li bontšitse seobetainee ka nkela methionine sebaka ho metabolism ea liphoofolo.

Betainee ka nkela methionine sebaka ka botlalo phepelong ea methyl. Ka lehlakoreng le leng, methionine e sebelisoa e le substrate ho etsa liprotheine, 'me ka lehlakoreng le leng, e nka karolo ho methyl metabolism e le mofani oa methyl.Betainee ka khothalletsa ts'ebetso ea betaine homocysteine ​​methyltransferase sebeteng le ho fana ka methyl e sebetsang hammoho, e le hore methionine demethylation sehlahisoa sa homocysteine ​​e ka ba methylated ho theha methionine ho tloha qalong, e le ho tsoela pele ho fana ka methyl bakeng sa metabolism ea 'mele ka tekanyo e lekanyelitsoeng ea methionine e le sephethephethe le betaine e le mohloli oa protheine e sebelisoang haholo ho methi. methionine le ho sebelisa matla. Hammoho, betaine e senyeha le ho feta kamora ho ba methylated ho hlahisa serine le glycine, ebe e eketsa bongata ba li-amino acid maling (kamoun, 1986).

Betaine e ekelitse litaba tsa methionine, serine le glycine serum. Puchala et al. E bile le litlamorao tse tšoanang tsa liteko ho linku. Betaine e ka eketsa li-amino acid tse kang arginine, methionine, leucine le glycine ka serum le kakaretso ea li-amino acid ka serum, ebe e ama ho tsoa ha auxin;Betainee ka 'na ea khothalletsa ho fetoloa ha aspartic acid ho n-methylaspartic acid (NMA) ka matla a methyl metabolism,' me NMA e ka ama sebopeho le excretion ea auxin ho hypothalamus, ebe joale boemo ba auxin 'meleng.
