ʻO Boc-D-Tyr(Bzl)-OH(Boc-D-Tyr(Bzl)-OH) he mea hoʻohuihui kino. Ua like kona mau waiwai kemika me nā ʻakika amino i pale ʻia e Boc.

 

ʻO Boc-D-Tyr(Bzl)-OH he mea hoʻopuka D-tyrosine me kahi hui pale (Boc). Hiki ke hoʻohana ʻia i mea hoʻomaka a i ʻole waena no ka peptide synthesis. Hiki i nā pūʻulu pale Boc ke pale i ka amide nitrogen a i ʻole nā ​​hui hana ʻē aʻe i ka wā o ka synthesis e pale ai i nā hopena kikoʻī ʻole. Eia kekahi, hiki ke hoʻohana ʻia ʻo Boc-D-Tyr (Bzl) -OH i ka noiʻi lāʻau lapaʻau a me ka synthesis o nā peptides bioactive.

 

ʻO ke ʻano maʻamau o ka hoʻomākaukau ʻana iā Boc-D-Tyr(Bzl)-OH ma ka hana ʻana i kahi tyrosine pale ʻia N-alpha me ka waiʻona benzyl. ʻO ka mea mua, pale ʻia ka hui amino o tyrosine a laila hoʻopili ʻia me ka waiʻona benzyl ma lalo o nā kūlana kūpono e hana i ka huahana i makemake ʻia. ʻO ka hope, ua wehe ʻia ka pūʻulu pale o ka hui amino e hāʻawi i ka Boc-D-Tyr(Bzl)-OH.

 

E pili ana i ka ʻike palekana, ʻo Boc-D-Tyr(Bzl)-OH kahi kemika e pono e hana ʻia i loko o kahi keʻena hana a hoʻokō i nā lula hana palekana lab. He mea hoʻonāukiuki paha ia i ka ʻili, nā maka a me ka ʻōnaehana hanu, no laila pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima lab a me nā aniani pale. I ka lawelawe ʻana a mālama ʻana i nā pūhui, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā kumu hoʻoheheʻe a i ʻole nā ​​​​mea hiki ke puhi ʻia. Inā hanu a komo i loko o ka maka a i ʻole ka waha, e holoi koke me ka wai nui a e ʻimi i ke kōkua olakino inā pono.
