Hoʻolauna

ʻO Boc-Gly-Gly-OH, ʻike ʻia ʻo Boc-Gly-Gly-OH(N-tert-butyloxycarbonyl-glycyl-glycine, Boc-Gly-Gly-OH no ka pōkole), he mea kemika. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

1. ʻAno:

ʻO Boc-Gly-Gly-OH he paʻa keʻokeʻo a keʻokeʻo me kahi helu heheʻe kiʻekiʻe a haʻahaʻa haʻahaʻa. Paʻa ia ma ka lumi wela, akā hiki ke hoʻohaʻahaʻa ma lalo o ka wela kiʻekiʻe, ka lā pololei a i ʻole ka ʻāina humid.

 

2. E hoʻohana:

ʻO Boc-Gly-Gly-OH kahi hui pale amino acid maʻamau. Hoʻohana ʻia ia e pale i ka pūʻulu amino o glycylglycine i ka synthesis kemika e pale i kāna ʻaoʻao ʻaoʻao i ka hopena kemika. I ka wā o ka synthesis o kahi polypeptide a i ʻole protein, hiki ke hoʻohui ʻia kahi Boc-Gly-Gly-OH ma ke ʻano he pūʻulu pale a laila hoʻoneʻe ʻia ma lalo o nā kūlana kūpono e hiki ai ke hoʻonui ʻia ke kaulahao polypeptide.

 

3. Ke ʻano hoʻomākaukau:

Hana ʻia ka hoʻomākaukau ʻana o Boc-Gly-Gly-OH e nā ʻano synthesis organik. ʻO kekahi ʻano hana maʻamau o ka hoʻomākaukau ʻana, ʻo ia ka hoʻokaʻawale ʻana i nā pūʻulu hydroxyl ʻelua o ka glycine me kahi Boc-anhydride (tert-butyloxycarbonyl anhydride) e lilo i Boc-Gly-Gly-OH. Pono e hoʻomaluʻia nā kūlana hopena i ka wā o ka hoʻomākaukauʻana e hōʻoia i ka hua a me ka maʻemaʻe.

 

4. ʻIke palekana:

Palekana ʻo Boc-Gly-Gly-OH ma lalo o nā kūlana hoʻokolohua maʻamau, akā pono e hoʻolohe ʻia kēia mau mea:

- Hiki i kēia hui ke hoʻonāukiuki i ka ʻili, nā maka a me nā ʻāpana hanu, no laila e hoʻohana i nā mea pale pono e like me nā mīkina lima lima a me nā maka aniani ke ʻike ʻia.

- Hōʻalo i ka hoʻopili ʻana me nā mea oxidants a i ʻole nā ​​​​mea hiki ke puhi ʻia i ka wā o ka hoʻohana ʻana a i ʻole ka mālama ʻana i mea e pale aku ai i nā kūlana pōʻino e like me ke ahi a pahū paha.

-Ka mālama pono a me ka hoʻolei ʻana i nā mea i koe a me nā ʻōpala i loko o ka hale hana, e hahai ana i nā hana palekana a me nā lula.
