ʻO Trit-butoxycarbonyl-L-seric acid benzyl ester (ʻike pū ʻia ʻo BOC-L-serine benzyl ester) he mea hoʻohuihui. Loaʻa iā ia nā waiwai penei:

 

1. Nānā: keʻokeʻo i nā kristal melemele māmā a i ʻole ka pauka crystalline.

 

Hoʻohana nui ʻia ka trit-butoxycarbonyl-L-seric acid benzyl no ka peptide synthesis a me ka peptide synthesis reactions ma ke kahua o ka synthesis organik. Hana ia ma ke ʻano he pūʻulu pale i ka peptide chain elongation reactions e pale i nā pūʻulu hana ʻaoʻao o nā waikawa amino. I loko o ke kaʻina hana synthesis, inā ʻaʻole pono e hoʻololi ʻia nā waikawa amino ʻē aʻe i loko o ke kaʻina peptide target i ka hopena, hiki i ka tert-butoxycarbonyl-L-seric acid benzyl ke pale pono iā L-serine.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka tert-butoxycarbonyl-L-serene benzyl ka mea maʻamau ma o ka hoʻoulu ʻana a me ka hopena esterification o nā waikawa amino. ʻO ke ʻano hoʻomākaukau kikoʻī hiki ke hana i ka L-serine me ka tert-butoxycarbonyl chlorinator e hana i ka paʻakai tert-butoxycarbonyl amino acid, a laila e hana me ka benzyl alcohol e loaʻa ai ka tert-butoxycarbonyl-L-serene benzyl.

 

ʻIke palekana: ʻO Trit-butoxycarbonyl-L-seric acid benzyl ka mea maʻamau i palekana ma lalo o ka hana pololei. Hiki ke hoʻonāukiuki i ka maka a me ka ʻili a pono e mālama pono i ka wā e hana ai. Pono e hana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pale i ka inhalation a i ʻole ka hoʻopili ʻana. I ka wā o ka mālama ʻana, pono e hoʻopaʻa paʻa ʻia a paʻa i ka wela a me ke ahi.
