ʻO N-acetyl-L-tryptophan kahi amino acid maoli i kapa ʻia ʻo NAC i ka kemika. ʻO kēia ka hoʻolauna ʻana i ke ʻano, hoʻohana, hana hana, a me ka ʻike palekana o NAC:

ʻAno maikaʻi:
ʻO ka N-acetyl-L-tryptophan kahi kala ʻole i ka pauka crystalline melemele māmā i hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe polar.

Hoʻohana: Hiki i ka N-acetyl-L-tryptophan ke hoʻomaikaʻi i ke ʻano o ka ʻili a hoʻemi i ka ʻelemakule a me ka pigmentation.

Hanana:
ʻO ka hoʻomākaukau ʻana o N-acetyl-L-tryptophan e loaʻa pinepine ʻia ma ka hana ʻana i ka L-tryptophan me ka acetic anhydride. Ma ka pae kiko'ī, hoʻopili ʻo L-tryptophan me ka acetic anhydride i mua o kahi catalyst kūpono i ka mahana kūpono a me ka manawa pane e hana ai i kahi huahana, a loaʻa ka huahana hope ma o ka crystallization a me ka hoʻomaʻemaʻe.

ʻIke palekana:
Mālama ʻia ka N-acetyl-L-tryptophan ma lalo o nā kūlana maʻamau o ka hoʻohana. Ma ke ʻano he mea kemika, pono nā mea hoʻohana e hoʻokō i nā kaʻina hana palekana kūpono. Pono e mālama ʻia e pale i ka inhalation, pili me ka ʻili a me nā maka, a me ka mālama ʻana i kahi kaiapuni maikaʻi i ka wā e lawelawe ai, mālama a mālama ʻana i ka mea. Inā loaʻa nā ulia, pono e lawe koke ʻia nā hana kōkua mua kūpono a pono e nīnau i ke alakaʻi a ke kauka.
