Glutamic acid ke amino acid ea bohlokoa haholo e nang le thepa e latelang:

 

Lintho tsa lik'hemik'hale: Glutamic acid ke phofo e tšoeu ea kristale e qhibilihang habonolo metsing. E na le lihlopha tse peli tse sebetsang, e 'ngoe ke sehlopha sa carboxyl (COOH)' me e 'ngoe ke sehlopha sa amine (NH2), se ka kenyang letsoho liketsong tse sa tšoaneng tsa lik'hemik'hale e le acid le setsi.

 

Thepa ea fisioloji: Glutamate e na le mesebetsi e fapaneng ea bohlokoa linthong tse phelang. Ke e 'ngoe ea li-block tsa motheo tse etsang liprotheine' me e ameha taolong ea metabolism le tlhahiso ea matla 'meleng. Glutamate e boetse ke karolo ea bohlokoa ea li-neurotransmitters tse ka amang ts'ebetso ea neurotransmission bokong.

 

Mokhoa: Asiti ea Glutamic e ka fumanoa ka metsoako ea lik'hemik'hale kapa ea ntšoa mehloling ea tlhaho. Mekhoa ea ho kopanya lik'hemik'hale hangata e kenyelletsa karabelo ea mantlha ea organic synthesis, joalo ka karabelo ea condensation ea li-amino acid. Mehloli ea tlhaho, ka lehlakoreng le leng, e hlahisoa haholo ke ho belisoa ke likokoana-hloko (mohlala E. coli), tse nkiloeng ebe li hloekisoa ho fumana glutamic acid ka bohloeki bo phahameng.

 

Tlhahisoleseding ea Tšireletseho: Glutamic acid ka kakaretso e nkoa e sireletsehile ebile e se chefo 'me e ka sebelisoa ka mokhoa o tloaelehileng ke' mele oa motho. Ha u sebelisa glutamate, hoa hlokahala ho latela molao-motheo oa ho iteka le ho ela hloko ho noa ho feteletseng. Ho phaella moo, bakeng sa baahi ba khethehileng (joaloka masea, bakhachane, kapa batho ba nang le mafu a itseng), e lokela ho sebelisoa tlas'a tataiso ea ngaka.
