• 甜菜堿

  Several enzymes are involved in the betain synthesis, as phosphoethanolamine N-methyltransferase (PEAMT) catalyzes the phosphoethanolamine to choline which is vital for betain synthesis, Choline is then catalyzed by choline monooxygenase (CMO) to betaine aldehyde, and finally catalyzed by betaine aldehyde dehydrogenase (BADH) to betain, and PEAMT and CMO play key roles in accumulation of betain.
  甜菜堿郃成涉及多個(gè)酶的作用,磷酸乙醇胺N-甲基轉(zhuǎn)移酶(PEAMT)是郃成膽堿的關(guān)鍵酶,膽堿單加氧酶(CMO)則催化膽堿氧化爲(wèi)甜菜堿醛,最後由甜菜堿醛脫氫酶(BADH)作用氧化爲(wèi)甜菜堿,其中PEAMT和CMO對(duì)甜菜堿積累起著決定性作用。
