Hoʻolauna

ʻO ka waikawa glutamic kahi amino nui loa i loaʻa nā waiwai penei:

 

Nā waiwai kemika: ʻO ka waikawa Glutamic he pauka keʻokeʻo keʻokeʻo e hiki ke hoʻoheheʻe ʻia i ka wai. ʻElua mau pūʻulu hana, hoʻokahi pūʻulu carboxyl (COOH) a ʻo kekahi pūʻulu amine (NH2), hiki ke komo i nā hopena kemika like ʻole me ka waikawa a me ka base.

 

Nā waiwai kino: He ʻano hana koʻikoʻi ka Glutamate i nā mea ola. ʻO ia kekahi o nā poloka kūkulu kumu e hana ai i nā protein a komo i ka hoʻoponopono o ka metabolism a me ka hana ʻana o ka ikehu i loko o ke kino. ʻO Glutamate kekahi mea nui o nā neurotransmitters e hiki ke hoʻopili i ke kaʻina neurotransmission i ka lolo.

 

Ke Kaʻina Hana: Hiki ke kiʻi ʻia ka ʻakika glutamic ma ka synthesis kemika a i ʻole ka unuhi ʻia mai nā kumu kūlohelohe. Hoʻokomo pinepine ʻia nā ʻano hana hoʻoheheʻe kemika i nā ʻano hoʻohālikelike kūlohelohe kumu, e like me ka hopena condensation o nā waikawa amino. ʻO nā kumu kūlohelohe, ma ka ʻaoʻao ʻē aʻe, ua hana nui ʻia e ka fermentation e nā microorganisms (eg E. coli), a laila lawe ʻia a hoʻomaʻemaʻe ʻia no ka loaʻa ʻana o ka glutamic acid me ka maʻemaʻe kiʻekiʻe.

 

ʻIke palekana: ʻO ka waika glutamic ka mea maʻamau i manaʻo ʻia he palekana a ʻaʻohe mea ʻawaʻawa a hiki ke hoʻololi ʻia e ke kino kanaka. I ka hoʻohana ʻana i ka glutamate, pono ia e hahai i ke kumu o ka hoʻohaʻahaʻa a e makaʻala i ka lawe nui ʻana. Eia kekahi, no nā poʻe kūikawā (e like me nā kamaliʻi, nā wahine hāpai, a me nā poʻe me nā maʻi kūikawā), pono e hoʻohanaʻia ma lalo o ke alakaʻi a ke kauka.
