ʻO ka N-acetyl-L-glutamic acid he mea kemika. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka N-acetyl-L-glutamic acid:

ʻAno maikaʻi:
ʻIke: N-acetyl-L-glutamic acid aia ma ke ʻano o nā keʻokeʻo keʻokeʻo a i ʻole nā ​​pauka crystalline.
Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe waiʻona e like me ka ethanol a me ka methanol.
Nā Waiwai Kemika: N-acetyl-L-glutamic acid he amino acid derivative i ʻakika, hiki iā ia ke hana me nā kumu a me nā ion metala.

E hoʻohana:

Hanana:
Nui nā ʻano hana no ka hoʻomākaukau ʻana i ka waika N-acetyl-L-glutamic, kahi o ia mea i hoʻohana maʻamau ʻia e ka hopena esterification o ka glutamic acid a me ka acetic anhydride.

ʻIke palekana:
E hahai i nā kaʻina hana kūpono a me nā hana pale pilikino i ka wā e hoʻohana ai.
Hōʻalo i ka pili ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu, a pale i ka inhalation a i ʻole ka ʻai ʻana.
I ka hoʻohana ʻana a i ʻole ka lawelawe ʻana i ka mea hoʻohui, e hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia a hoʻohana i nā lako pale pilikino kūpono.
Inā loaʻa kekahi pilikia kino a ulia paha, e ʻimi koke i ka lāʻau lapaʻau a lawe mai i ka pepa ʻikepili palekana o ka pūhui i kahi hale lapaʻau.
