ʻO FMOC-O-tert-butyl-L-threonine kahi hui me nā waiwai penei:

 

Nānā: Paʻa keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo.

Solubility: hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik, e like me ka dimethyl sulfoxide, N, N-dimethylformamide, etc., hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

Ka hoʻohana ʻana i ka FMOC-O-tert-butyl-L-threonine:

ʻO ka peptide synthesis: ma ke ʻano he hui pale, hoʻohana ʻia no ka synthesis o nā kaʻina peptide a me nā hopena hoʻololi ion i loko o lākou.

Ka noiʻi biochemical: no ka synthesis a me ke aʻo ʻana i nā peptides kūlohelohe a me nā protein.

 

Ke ala hoʻomākaukau o FMOC-O-tert-butyl-L-threonine:

Hiki ke hoʻohui ʻia ʻo FMOC-O-tert-butyl-L-threonine e nā pae aʻe:

Hoʻopili ʻia ʻo L-threonine me FMOC-O-tert-butyl-N-hydroimide e hana i ka ester pauka FMOC-O-tert-butyl-L-threonine-N-agar.

FMOC-O-tert-butyl-L-threonine-N-agar pauka ester ua hydrolyzed e loaa FMOC-O-tert-butyl-L-threonine.

 

ʻIke palekana o FMOC-O-tert-butyl-L-threonine:

Hōʻalo i ka hoʻopili pololei ʻana me ka ʻili a me nā maka, hiki mai ka huhū a me nā hopena maʻi.

E ʻoluʻolu e hana ma kahi e hoʻoheheʻe maikaʻi ʻia a pale i ka inha ʻana i nā mahu a i ʻole ka lepo.
