Hoʻolauna

N-(α)-Boc-L-aspartyl he amino acid derivative, nona nā waiwai penei:

ʻAno: keʻokeʻo i ka pauka crystalline melemele;

Solubility: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe maʻamau, e like me ka dimethylformamide (DMF) a me ka methanol;

Paʻa: Paʻa i loko o kahi maloʻo, akā hiki ke maʻa i ka makū i nā kūlana haʻahaʻa, pono e pale ʻia ka lōʻihi o ka ʻike ʻana i ka haʻahaʻa kiʻekiʻe.

ʻO kāna mau noi nui:

ʻO ka peptide synthesis: ma ke ʻano he waena i ka synthesis o polypeptides, hiki ke hoʻohana ʻia e kūkulu i ka ulu ʻana o ke kaulahao peptide;

Ka noiʻi olaola: ma ke ʻano he mea nui no ka hoʻohui ʻana i ka protein a me ka noiʻi ʻana i loko o ka hale hana.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka waikawa N-(α)-Boc-L-aspartoyl ka mea maʻamau e hoʻokō ʻia ma ka hana ʻana i ka waikawa L-aspartyl me Boc-protection reagent.

 

ʻIke palekana: N-(α)-Boc-L-aspartoyl acid ka mea maʻamau i manaʻo ʻia he hui me ka haʻahaʻa ʻona. Ma ke ʻano he reagent kemika, pono e mālama ʻia nā kaʻina hana palekana i nā hale hana kemika i ka wā e lawelawe ai a hoʻohana iā lākou. Pono e pale ʻia ka pili ʻana i ka ʻili a me ka inhalation o ka lepo. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā mīkina lima lab, nā aniani, a me nā pale pale i ka wā e hoʻohana ai. Inā loaʻa ka pilikia a i ʻole ka ʻai ʻana, e ʻimi koke i ka lāʻau lapaʻau.
