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 khothaletsa ts'ebetso ea betaine homocysteine ​​methyltransferase sebeteng le ho fana ka methyl e sebetsang hammoho, e le hore sehlahisoa sa methionine demethylation 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 joalo ka sejari. le betaine e le mohloli oa methyl, Joale, boholo ba methionine bo sebelisetsoa ho etsa liprotheine, tse ka bolokang 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.
