Hoʻolauna

ʻO ka N-Acetyl-L-tyrosine kahi mea hoʻoheheʻe amino acid maoli i hana ʻia e ka hopena o ka tyrosine a me ka acetylating agents. ʻO ka N-acetyl-L-tyrosine he pauka keʻokeʻo keʻokeʻo ʻaʻole ʻono a ʻala ʻole. Hiki ke hoʻoheheʻe maikaʻi ʻia a hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol.

 

Hiki ke kiʻi ʻia ka hoʻomākaukau ʻana o N-acetyl-L-tyrosine ma ka hana ʻana i ka tyrosine me kahi mea acetylating agent (eg, acetyl chloride) ma lalo o nā kūlana alkaline. Ke pau ka hopena, hiki ke hoʻomaʻemaʻe ʻia ka huahana ma o nā ʻanuʻu e like me ka crystallization a me ka holoi ʻana.

 

Ma ke ʻano o ka palekana, ua manaʻo ʻia ʻo N-acetyl-L-tyrosine he pūhui palekana a maʻamau ʻaʻole ia he hopena koʻikoʻi. ʻO ka hoʻohana nui ʻana a i ʻole ka hoʻohana lōʻihi e hiki ke hōʻeha i kekahi pilikia e like me ke poʻo, ʻeha o ka ʻōpū, etc.
