Hoʻolauna

ʻO ka Fluorene methoxycarbonyl-oxotert-butyl-tyrosine he pūhui kemika i hoʻopau pinepine ʻia ʻo FMOC-Tyr(tBu)-OH. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: Paʻa keʻokeʻo a keʻokeʻo paha.

- Hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka dimethyl sulfoxide a me ka dimethylformamide.

 

E hoʻohana:

- Ka pale ʻana i nā pūʻulu i ka synthesis kemika: Hiki ke hoʻohana ʻia nā pūʻulu FMOC e pale i nā pūʻulu amino i loko o nā pūhui phenolic e pale aku iā lākou mai ka pane ʻana. Hiki ke hoʻohana ʻia ʻo FMOC-Tyr(tBu)-OH i mea hoʻomaka no ka hoʻomākaukau ʻana i nā kaulahao peptide i ka synthesis kemika.

 

Hanana:

Hiki ke hoʻokō ʻia ke ʻano hoʻomākaukau o FMOC-Tyr(tBu)-OH e nā ʻanuʻu aʻe:

- Hoʻopili ʻia ka Fluorenyl chloride (FMOC-Cl) me ka tert-butyl (tBu-NH2) e hāʻawi i ka fluorenylmethoxycarbonyl-tert-butichsyl (FMOC-tBu-NH-).

- A laila, e hana i ka hopena FMOC-tBu-NH- me tyrosine (Tyr-OH) e hoʻohua i ka FMOC-Tyr(tBu)-OH.

 

ʻIke palekana:

- ʻO ka hoʻohana ʻana o FMOC-Tyr (tBu)-OH e pili ana i ka hoʻokō ʻana i nā kuʻina palekana palekana.

- Hōʻalo i ka pili ʻana me ka ʻili a me nā maka, a hoʻohana i nā mīkina lima pale a me nā maka aniani ke hoʻohana.

- E hoʻohana i kahi wahi e hoʻoheheʻe maikaʻi ʻia, mamao mai ke ahi a me nā mea puhi.

- ʻAʻole pono e hoʻokuʻu ʻia i loko o ke kaiapuni a pono e mālama ʻia a hoʻopau ʻia e like me nā lula kūloko.
