• Yooj yim rau automation, ua kom muaj zog ntxiv.
• Simplifies purification txheej txheem.
Qhov tsis zoo:
• Yuav tsum muaj cov cuab yeej tshwj xeeb.
• Tej zaum yuav muaj kev txwv ntawm hom kev hloov kho uas tuaj yeem qhia tau.
Txoj Kev 4: Chemoenzymatic Synthesis
Chemoenzymatic synthesis muab cov tshuaj thiab cov txheej txheem enzymatic los ua kom muaj zog ntawm ob txoj hauv kev. Txoj kev hybrid no tuaj yeem muab qhov sib npaug ntawm qhov ua tau zoo thiab qhov tshwj xeeb.
Qhov zoo:
• Ua ke qhov tseeb ntawm cov tshuaj synthesis nrog kev xaiv ntawm enzymatic synthesis.
• Yuav ua tau zoo dua li siv ob txoj kev ib leeg.
Qhov tsis zoo:
• Complexity hauv optimizing tej yam kev mob rau ob qho tib si tshuaj thiab enzymatic kauj ruam.
• Tej zaum tus nqi siab dua vim qhov xav tau ntawm cov tshuaj reagents thiab enzymes.
