Hoʻolauna

ʻO Boc-L-threonine kahi mea hoʻohuihui. He paʻa keʻokeʻo e hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe e like me dimethylthionamide (DMSO), ethanol a me chloroform.

Hiki ke hoʻomākaukau ʻia e like me Boc-L-threonine e ka hopena o nā hui pale amino acid.

 

ʻO kahi ala e hoʻomākaukau ai i ka Boc-L-threonine, ʻo ia ka hana mua ʻana i ka threonine me ka ʻakika Boc ma o ka hopena acid-catalyzed e hana i ka ester Boc threonine pili, a laila e loaʻa iā Boc-L-threonine ma o ka hopena hydrolysis alkaline.

He kemika ia a pono e mālama ʻia i loko o kahi keʻena hoʻokolohua maikaʻi me nā lako pale pilikino kūpono e like me nā mīkina lima lab a me nā maka aniani. E hōʻalo i ka hoʻopili ʻana me ka ʻili a me nā maka, a pale i ka hanu ʻana i ko lākou lepo a i ʻole ke kinoea. Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.
