Hoʻolauna

He hui kino ia i pani ʻia ai ka pūʻulu carboxyl (-COOH) i loko o ka mole alanine i loko o ka hale e kahi hui benzyloxycarbonyl (-Cbz).

 

Nā waiwai o ka hui:

-Nani: ʻO ka pauka aniani keʻokeʻo

-Ke kumu molekole: C12H13NO4

-Molecular kaumaha: 235.24g/mol

-Lae hehee: 156-160 ° C

 

ʻO nā mea hoʻohana nui e like me kēia:

-Ma ke kahua o ka synthesis organik, hiki ke hoʻohana ʻia ma ke ʻano he waena no ka synthesis o nā mea hoʻohui organik paʻakikī.

-Ma ke ʻano he hui pale no nā lāʻau polypeptide synthetic, hoʻohana ʻia ia e pale i nā koena alanine.

-No ka noiʻi ʻana a me ka hoʻomākaukau ʻana i nā molekole organik ʻē aʻe.

 

Hiki ke hoʻokaʻawale ʻia ke ʻano hoʻomākaukau i nā ʻanuʻu penei:

1. ʻO ka hopena o ka benzyl chlorocarbamate me ka sodium carbonate e loaʻa ai ka benzyl N-CBZ-methylcarbamate (N-benzyloxycarbonylmethylaminoformate).

2. E hana i ka huahana i loaʻa ma ka ʻanuʻu mua me ka solution sodium hydroxide e loaʻa ai ka N-CBZ-β-alanine.

 

E pili ana i ka ʻike palekana:

-ʻO ka mea maʻamau i manaʻo ʻia he palekana, akā pono mau nā hana hana kūpono.

-E pale i ka pili ʻana me ka ʻili, nā maka a me ka waha i ka wā e hoʻohana ai.

-E hoʻohana i nā mīkina lima pale kūpono, nā maka aniani, a me nā ʻaʻahu lab ke hana i nā hoʻokolohua.

-E hōʻalo i ka hanu ʻana i ka lepo mai ka hui.

- Pono e mālama ʻia ka pūhui ma kahi maloʻo, maloʻo, a hoʻokaʻawale ʻia mai nā mea hiki ke ahi, nā mea ʻona a me nā mea ʻē aʻe.

 

Pono e hoʻomaopopo ʻia ʻo ka ʻike i hāʻawi ʻia ma ʻaneʻi no ka ʻike wale nō, a ʻo ka manual hoʻokolohua kūpono a me ka pepa ʻikepili palekana kemika pono e kūkākūkā ʻia ma mua o ka hoʻohana ʻana i ka pūhui, a e like me nā lula palekana no ka hana.
