Hoʻolauna
ʻO D-tert-leucine (D-tert-leucine) he mea hoʻohuihui mea ola me ke ʻano kemika C7H15NO2 a me ke kaumaha molekala o 145.20g/mol. He molekele chiral, ʻelua stereoisomers, ʻo D-tert-leucine kekahi o lākou. ʻO ke ʻano o ka D-tert-leucine penei:
1. Nānā: ʻO ka D-tert-leucine he aniani kala ʻole a i ʻole ka pauka crystalline keʻokeʻo.
2. Solubility: hiki ke hoʻoheheʻe iki i ka wai, hiki ke hoʻoheheʻe iki i ka ethanol a me nā mea hoʻoheheʻe Etera.
3. Ka helu heheʻe: ʻO ka helu heheʻe o ka D-tert-leucine ma kahi o 141-144 ° C.
Hoʻohana nui ʻia ʻo D-tert-leucine no Chiral synthesis i ka synthesis organik a me ka hana lāʻau lapaʻau. Loaʻa iā ia nā noi nui ma Enantioselective Catalytic Reactions a me ka noiʻi lāʻau. ʻO nā hoʻohana kikoʻī penei:
1. Chiral synthesis: Hiki ke hoʻohana ʻia ka D-tert-leucine ma ke ʻano he chiral catalysts a i ʻole Chiral reagents no ka synthesis o nā pūhui chiral.
2. ʻO ka hana lāʻau lapaʻau: D-tert-leucine ua hoʻohana nui ʻia i ka noiʻi lāʻau lapaʻau a me ka hoʻohui ʻana i ka lāʻau, no ka hoʻohui ʻana o nā molekala lāʻau chiral.
ʻO ke ʻano o ka hoʻomākaukau ʻana i ka D-tert-leucine ma o ka synthesis kemika a i ʻole fermentation. ʻO ke ʻano hana synthesis kemika ka mea maʻamau i ka hopena o nā mea waiwai synthetic e loaʻa ai ka huahana i makemake ʻia. ʻO ka Fermentation ka hoʻohana ʻana i nā microorganisms (e like me Escherichia coli) e hoʻololi i nā substrate kikoʻī e hana ai i ka D-tert-leucine.
E pili ana i ka ʻike palekana, haʻahaʻa ka ʻawaʻawa o D-tert-leucine, a ke manaʻoʻiʻo ʻia ʻaʻohe mea ʻino i ke kino o ke kanaka. Eia nō naʻe, pono ʻoe e hoʻolohe i ka pale pilikino i ka wā o ka hana, e pale i ka pili pono ʻana me ka ʻili a me nā maka, a mālama i nā kūlana ea maikaʻi. E hahai i nā kaʻina hana palekana i ka wā e hoʻohana ai, a e hana i nā hana pale kūpono e pili ana i ka nui a me ka noʻonoʻo i hoʻohana ʻia. I ka hihia o ka hoʻopili ʻana a i ʻole ka ʻai ʻana, e ʻoluʻolu e ʻimi i ka lāʻau lapaʻau i ka manawa a lawe i ka ʻike palekana pili i ka haukapila.
