Nhanganyaya
D-tert-leucine(D-tert-leucine) inhengo yeorganic ine kemikari formula C7H15NO2 uye molecular uremu hwe145.20g/mol. Iyo chiral molecule, kune maviri stereoisomers, D-tert-leucine imwe yacho. Chimiro cheD-tert-leucine ndeichi:
1. Chitarisiko: D-tert-leucine ikristaro isina ruvara kana kuti white crystalline powder.
2. Solubility: inogona kunyungudika zvishoma mumvura, inonyungudika zvishoma mu ethanol neEther solvents.
3. Kunyungudika: Nzvimbo yakanyunguduka yeD-tert-leucine inenge 141-144°C.
D-tert-leucine inonyanya kushandiswa kuChiral synthesis mune organic synthesis uye kugadzira mishonga. Iyo ine yakakosha mashandisirwo muEnantioselective Catalytic Reactions uye tsvakurudzo yezvinodhaka. Mashandisirwo chaiwo ndeaya anotevera:
1. Chiral synthesis: D-tert-leucine inogona kushandiswa sechiral catalysts kana Chiral reagents nokuda kwekugadzirwa kwechiral compounds.
2. Kugadzira zvinodhaka: D-tert-leucine inoshandiswa zvakanyanya mukutsvakurudza kwezvinodhaka uye kushandiswa kwezvinodhaka, nokuda kwekugadzirwa kwechiral drug molecules.
Nzira yekugadzirira D-tert-leucine inonyanya kuburikidza nemakemikari synthesis kana kuvirisa. Iyo kemikari synthesis nzira inowanzoita nhevedzano yemaitiro ekugadzira mbishi zviwanikwa kuti uwane icho chinonangwa chigadzirwa. Kuvirisa kushandiswa kwezvipembenene (zvakadai seEscherichia coli) kugadzira masubstrates chaiwo kuti abudise D-tert-leucine.
Nezve ruzivo rwekuchengetedza, huturu hweD-tert-leucine hwakaderera, uye zvinotendwa kuti hapana kukuvadza kuri pachena kumuviri wemunhu. Nekudaro, iwe unofanirwa kuramba uchiteerera kune kuchengetedzwa kwemunhu panguva yekushanda, dzivisa kutarisana zvakananga neganda nemeso, uye kuchengetedza mamiriro akanaka ekufema. Tevedzera nzira dzakachengeteka dzekushanda panguva yekushandiswa, uye tora matanho ekudzivirira akakodzera zvichienderana nehuwandu uye kusungwa kunoshandiswa. Kana ukangosangana netsaona kana kunwa, ndapota tsvaga kurapwa nenguva uye uendese ruzivo rwekuchengetedza rwunoenderana kuchipatara.
