Cov kev tshawb fawb hauv cov nas tau lees paub tias betaine feem ntau ua lub luag haujlwm ntawm methyl donor hauv daim siab thiab raug tswj hwm los ntawmbetainehomocysteine ​​methyltransferase (BHMT) thiab p-cysteine ​​sulfide β Synthetase (β Kev Tswj Xyuas ntawm cyst (mud et al., 1965). Qhov tshwm sim no tau lees paub hauv npua thiab qaib. Thaum cov methyl tsis txaus, lub cev tsiaj ua rau cov kua qaub hemiaminic siab txais cov methyl ntawm betaine los ntawm kev txhim kho cov haujlwm ntawm BHMT los tsim methionine thiab tom qab ntawd muab methyl. Thaum ntxiv cov betaine tsawg, vim muaj cov methyl tsawg hauv lub cev, lub siab ua rau lub sijhawm voj voog ntawm homocysteine ​​​​​​nce BMT kev ua ub no thiab siv betaine ua substrate, yog li muab cov methyl txaus rau cov khoom siv metabolism. Ntawm cov koob tshuaj siab, vim muaj kev ntxiv ntau ntawm exogenousbetaine, ntawm ib sab tes, lub siab muab methyl rau lub methyl receptor los ntawm kev txhim kho BHMT kev ua haujlwm, thiab ntawm qhov tod tes, ib feem ntawm homocysteine ​​​​​​tsim cysteine ​​​​​sulphide los ntawm txoj kev hloov pauv sulfur, yog li ua kom lub cev txoj kev hloov pauv methyl nyob rau hauv qhov sib npaug ruaj khov. Kev sim qhia tau hais tias nws muaj kev nyab xeeb los hloov ib feem ntawm methionine hauv cov khoom noj broiler os nrog betaine. Betaine tuaj yeem nqus tau los ntawm cov hlwb plab hnyuv qaib, txo qhov kev puas tsuaj ntawm cov tshuaj rau cov hlwb plab hnyuv, txhim kho kev ua haujlwm nqus ntawm cov hlwb plab hnyuv qaib, txhawb kev nqus cov as-ham, thiab thaum kawg txhim kho kev ua tau zoo thiab kev tiv thaiv kab mob ntawm qaib.

Betainetuaj yeem txhawb kev tso tawm ntawm GH, uas tuaj yeem txhawb kev tsim cov protein, txo qhov kev lwj ntawm cov amino acids thiab ua rau lub cev muaj qhov sib npaug zoo ntawm nitrogen. Betaine tuaj yeem ua rau cyclic adenosine monophosphate hauv daim siab thiab pituitary (ˆ Cov ntsiab lus ntawm am, yog li txhim kho kev ua haujlwm endocrine ntawm pituitary thiab txhawb kev tsim thiab tso tawm ntawm (h, thyroid stimulating hormone) los ntawm cov hlwb pituitary α SH thiab lwm yam tshuaj hormones tuaj yeem ua rau lub cev khaws cia nitrogen ntau ntxiv, yog li txhawb kev loj hlob ntawm cov tsiaj txhu thiab nqaij qaib. Qhov kev sim qhia tau hais tias betaine tuaj yeem ua rau cov theem ntawm serum h thiab IGF hauv npua ntau theem sib txawv, txhawb kev loj hlob ntawm npua ntau theem thiab txo qhov hnyav pub. Cov npua uas tsis tau noj mis, cov npua uas tab tom loj hlob thiab cov npua tiav lawm tau pub nrog cov khoom noj uas muaj betaine 8001000 thiab 1750ngkg, thiab qhov nce txhua hnub tau nce 8.71% N13 20% thiab 13.32%, qib GH hauv cov ntshav tau nce 46.15%, 102.11% thiab 58.33%, thiab qib IGF tau nce 38.74%, 4.75% thiab 47.95% (Yu Dongyou et al., 2001). Kev ntxiv betaine rau hauv pub kuj tseem tuaj yeem txhim kho kev ua haujlwm ntawm cov npua yug me nyuam, ua rau qhov hnyav yug me nyuam thiab qhov loj ntawm cov npua nyob, thiab tsis muaj kev cuam tshuam tsis zoo rau cov npua cev xeeb tub.

BetaineNws tuaj yeem txhim kho kev kam rau cov cell biological rau qhov kub thiab txias, ntsev ntau thiab osmotic ib puag ncig siab, ua kom cov enzyme ua haujlwm thiab lub zog kinetic ntawm cov macromolecules biological ruaj khov. Thaum lub siab osmotic ntawm cov cell nqaij hloov pauv, betaine tuaj yeem nqus tau los ntawm cov cell, tiv thaiv kev poob dej thiab ntsev nkag mus rau hauv cov cell, txhim kho kev ua haujlwm ntawm Na twj ntawm daim nyias nyias cell, tswj lub siab osmotic ntawm cov cell nqaij, tswj lub siab osmotic ntawm cov cell, txo kev ntxhov siab thiab txhim kho kev tiv thaiv kab mob.Betainemuaj cov yam ntxwv zoo ib yam li electrolyte. Thaum cov kab mob nkag mus rau hauv txoj hnyuv, nws muaj cov nyhuv tiv thaiv osmotic rau cov hlwb ntawm txoj hnyuv npua. Thaum cov menyuam npua muaj dej poob thiab ion tsis sib npaug vim raws plab, betaine tuaj yeem tiv thaiv dej poob thiab tiv thaiv hyperkalemia los ntawm raws plab, yog li tswj thiab ruaj khov ion sib npaug ntawm txoj hnyuv thiab ua rau cov kab mob zoo hauv cov kab mob microbial ntawm txoj hnyuv npua hauv qab kev ntxhov siab weaning dominate. Cov kab mob phem yuav tsis nce ntau, tiv thaiv cov enzymes tso tawm hauv txoj hnyuv thiab kev ruaj khov ntawm lawv cov haujlwm, txhim kho kev loj hlob thiab kev txhim kho ntawm lub cev zom zaub mov ntawm cov menyuam npua weaned, txhim kho kev zom zaub mov thiab kev siv cov khoom noj, nce kev noj zaub mov thiab qhov hnyav nce txhua hnub, txo qis raws plab thiab txhawb kev loj hlob sai ntawm cov menyuam npua weaned.
