alpha-t-BOC-L-glutamine(CAS# 13726-85-7 ) hoʻolauna

ʻO ka N-BOC-L-glutamine kahi mea hoʻohui kino. Hiki ke noho paʻa ma ka lumi wela.

ʻO N-BOC-L-glutamine kahi hui me kahi hui hana amino pale. Hiki i kāna hui pale ke pale i ka reactivity o ka hui amino i nā hopena hope e hoʻomalu i ka koho a me ka hopena o ka hopena. I ka manawa e pono ai, hiki ke wehe ʻia ka hui pale ma o ka acid catalysis e hoʻihoʻi i ka hana o ka hui amino.

ʻO ke ala maʻamau no ka hoʻomākaukau ʻana i ka N-BOC-L-glutamine ka pale ʻana i ka L-glutamine ma o ka hoʻohana ʻana i kahi hui pale N-BOC. ʻO ka mea maʻamau, ua hana mua ʻia ka L-glutamine me N-BOC-Dimethylacetamide ma lalo o nā kūlana alkaline e hana ai i ka N-BOC-L-glutamine. A laila, hiki ke loaʻa nā huahana maʻemaʻe ma o ka crystallization, solvent evaporation, a me nā ʻano hana ʻē aʻe.

ʻIke palekana o N-BOC-L-glutamine: He haʻahaʻa kona ʻona. E like me nā mea kemika, pono ia e mālama pono. I ka wā o ka hana ʻana, pono e mālama ʻia nā kaʻina hana palekana lab e pale aku i ka pili ʻana i ka ʻili a me ka inhalation. Pono e mālama ʻia nā kūlana ea maikaʻi a pono e hoʻolako ʻia nā lako pale pilikino kūpono e like me nā mīkina lima a me nā maka aniani.
