Hoʻolauna

ʻO ka L-phenylalanine benzyl ester kahi mea hoʻohuihui. Aia i loko o kāna ʻano kemika kahi mole L-aspartic acid a me kahi hui esterified benzyl.

 

Loaʻa iā L-Benzyl aspartate ke ʻano o ka pauka crystalline keʻokeʻo i hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka chloroform ma ka lumi wela a hiki ke hoʻoheheʻe iki ʻia i ka wai. He derivative ia me ka waikawa amino maoli L-aspartic acid a hoʻokani i kahi hana koʻikoʻi koʻikoʻi i nā mea ola.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka L-benzyl aspartate ʻo ia ka hoʻololi ʻana i ka waikawa L-aspartic me ka waiʻona benzyl ma o ka hopena esterification. Hana ʻia ka hopena ma lalo o nā kūlana acidic a me ka hoʻohana ʻana i nā catalysts acid kūpono.

He kemika ia a pono e hoʻokuʻu ʻia e like me nā kuhikuhi hana kūpono a me nā protocol palekana. E hōʻalo i ka pili ʻana me ka ʻili a me nā maka, a hoʻokomo i nā mīkina lima pale, nā maka aniani, a me nā lole pale inā pono. Inā komo a inhaled, e ʻimi koke i ka lāʻau lapaʻau. Pono e mālama ʻia ma kahi maloʻo a maikaʻi ka makani, mai ka wela a me ke ahi.
