Hoʻolauna

ʻO ka N-acetyl-L-valine kahi hui kemika. He paʻa keʻokeʻo i hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik.

Hiki ke hoʻololi ʻia i loko o ka L-valine i loko o ke kino, kahi i komo i ka synthesis o nā protein a me nā peptides.

 

ʻElua mau ala nui no ka hoʻomākaukau ʻana i ka N-acetyl-L-valine: kemika synthesis a me ka enzymatic synthesis. Loaʻa ke ʻano hana synthesis kemika ma ka hoʻopili ʻana i ka L-valine me kahi reagent acetylation. ʻO ka Enzymatic synthesis, ma ka ʻaoʻao ʻē aʻe, hoʻohana i nā hopena enzyme-catalyzed e hana i ka acetylation i koho a maikaʻi.

 

ʻIke palekana: ʻO ka N-acetyl-L-valine ka mea maʻamau i manaʻo ʻia he haʻahaʻa ʻona. Inā pili ʻoe iā ia i ka wā o ka hoʻohana ʻana, pono e mālama ʻia e pale aku i ka hanu ʻana i ka lepo a i ʻole ka pili pono ʻana me ka ʻili a me nā maka. Pono e lawe ʻia nā hana palekana pilikino e like me nā mīkina lima, nā maka, a me nā maka aniani i ka wā e lawelawe ai i ka pūhui. Inā loaʻa ka pilikia ma muli o ka ʻai ʻana a i ʻole ka hoʻopili ʻana, pono ʻoe e ʻimi i ka lāʻau lapaʻau i ka manawa.
