ʻO ka N-Boc-L-aspartic acid he L-methionine derivative i loaʻa kahi hui pale N.

 

ʻAno maikaʻi:

ʻO N-Boc-L-methionine kahi paʻa keʻokeʻo i hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka methanol, ethanol, a me ka methylene chloride. Paʻa ia i nā kūlana acidic akā hydrolyzed i nā kūlana alkaline.

 

E hoʻohana:

ʻO N-Boc-L-methionine kahi hui pale amino acid i hoʻohana mau ʻia e pale ana i nā hui reactive ʻē aʻe i ka synthesis o nā pūhui organik.

 

Hanana:

ʻO ka hoʻomākaukau ʻana o N-Boc-L-methionine e loaʻa mau ʻia e ka hopena kemika o ka hui pale N-Boc ma L-methionine. ʻO ke ala maʻamau ka hoʻohana ʻana i ka Boc2O (N-butyldicarboxamide) a me kahi catalyst kumu e hāʻawi iā N-Boc-L-methionine ma hope o ka hopena.

 

ʻIke palekana:

ʻO ka N-Boc-L-methionine ka palekana ma lalo o nā kūlana hana hoʻokolohua maʻamau. Hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu a pono e mālama ʻia e pale aku i ka hoʻopili ʻana i ka wā e hoʻohana ai. E hoʻolohe i ka mālama ʻana i nā kikoʻī o ka hana hoʻokolohua palekana a hoʻolako ʻia me nā mea pale e pili ana.
