Isingeniso

I-Glutamic acid iyi-amino acid ebaluleke kakhulu enezici ezilandelayo:

 

Izici zamakhemikhali: I-Glutamic acid iyimpushana emhlophe eyikristalu encibilika kalula emanzini. Inamaqembu amabili asebenzayo, elinye iqembu le-carboxyl (COOH) kanti elinye iqembu le-amine (NH2), elingabamba iqhaza ekuphenduleni kwamakhemikhali okuhlukahlukene njenge-asidi nesisekelo.

 

Izakhiwo ze-physiological: I-Glutamate inemisebenzi ehlukahlukene ebalulekile ezintweni eziphilayo. Ingenye yezakhiwo eziyisisekelo ezakha amaprotheni futhi ihileleke ekulawuleni i-metabolism kanye nokukhiqizwa kwamandla emzimbeni. I-Glutamate nayo iyingxenye ebalulekile yama-neurotransmitters angathinta inqubo ye-neurotransmission ebuchosheni.

 

Indlela: I-Glutamic acid ingatholakala ngokuhlanganiswa kwamakhemikhali noma ikhishwe emithonjeni yemvelo. Izindlela zokwenziwa kwamakhemikhali zivame ukubandakanya ukusabela kokwakheka kwemvelo okuyisisekelo, njengokusabela kokujiya kwama-amino acid. Imithombo yemvelo, ngakolunye uhlangothi, ikhiqizwa kakhulu ngokuvutshelwa amagciwane (isib. E. coli), abese ekhishwa futhi ahlanzwe ukuze athole i-glutamic acid ngokuhlanzeka okuphezulu.

 

Ulwazi Lokuphepha: I-Glutamic acid ngokuvamile ibhekwa njengephephile futhi engeyona into enobuthi futhi ingashintshwa ngokujwayelekile umzimba womuntu. Uma usebenzisa i-glutamate, kuyadingeka ukulandela isimiso sokulinganisela futhi uqaphele ukudla ngokweqile. Ngaphezu kwalokho, kubantu abakhethekile (njengezinsana, abesifazane abakhulelwe, noma abantu abanezifo ezithile), kufanele kusetshenziswe ngaphansi kokuqondiswa udokotela.
