Trehalose: "Qab Zib ntawm Lub Neej" Tsav Kev Tsim Kho Tshiab Thoob Plaws Khoom Noj, Tshuaj thiab Tshuaj Pleev Xim

Trehalose, ib qho disaccharide ntuj uas tsis txo qis uas tseem hu ua "qab zib ntawm lub neej," txuas ntxiv mus tau txais kev nyiam ua ib qho khoom xyaw uas siv tau ntau yam, huv si thoob plaws hauv kev lag luam khoom noj, tshuaj, thiab kev saib xyuas tus kheej. Nws muaj nqis rau nws qhov kev ruaj khov zoo, noo noo, thiab kev khaws cia, nws tau dhau los ua ib qho kev daws teeb meem zoo rau cov neeg tsim cov tshuaj uas tsom mus rau kev txhim kho cov khoom zoo, txuas lub sijhawm txee, thiab ua kom tau raws li qhov kev thov ntawm cov neeg siv khoom rau cov khoom xyaw ntuj, pob tshab.

Cov tshuaj lom neeg hu ua D-(+)-trehalose anhydrous (CAS 99-20-7), trehalose muaj ob lub glucose molecule txuas nrog los ntawm α,1–1 glycosidic bond. Nws tshwm sim ntuj hauv cov fungi, yeast, algae, thiab qee yam invertebrates, qhov twg nws tiv thaiv cov cell thiab biomolecules los ntawm kev ntxhov siab heev xws li dehydration, freezing, thiab oxidation. Lub peev xwm bioprotective no txhais tau ncaj qha mus rau hauv kev siv tau hauv kev lag luam: nws ua kom cov protein, lipids, thiab carbohydrates ruaj khov nyob rau hauv cov txheej txheem ua thiab khaws cia hnyav.

Cov lus qhia tseem ceeb suav nrog lub ntsiab lus yaj ntawm 203 ° C, lub ntsiab lus kub ntawm 397.76 ° C (kwv yees li qub), qhov ceev ntawm 1.5800, thiab lub zog vapor ntawm 0.001 Pa ntawm 25 ° C. Nws yaj tau hauv dej, yaj me ntsis hauv 95% ethanol, thiab yuav luag tsis yaj hauv ether. Muaj ua hmoov dawb-rau-tawm-dawb nrog kev ntshiab siab (≥99%), trehalose ua tau raws li cov khoom noj khoom haus, tshuaj pleev ib ce, thiab tshuaj qib.

Hauv cov khoom noj thiab dej haus, trehalose ua haujlwm ua cov khoom ntub dej, cov khoom ruaj khov, thiab cov khoom zoo dua. Nws pab tswj cov dej noo, tiv thaiv kev ua kom pob zeb, thiab khaws cov saj thiab cov qauv qub ntawm cov khoom xws li cov khoom ci thiab cov khoom qab zib rau cov khoom qab zib khov, mis nyuj, thiab cov nqaij ua tiav. Raws li kev thawb kom txo cov piam thaj thiab cov qauv huv si nrawm dua, trehalose lub peev xwm los tswj cov khoom zoo yam tsis muaj qab zib ntau dhau ua rau nws yog cov khoom xyaw zoo tshaj plaws rau kev tsim khoom noj niaj hnub. Nws kuj ua haujlwm ua cov khoom qab zib me me, txo qhov xav tau ntxiv cov suab thaj thaum txhawb nqa cov lus qhia huv si.

Hauv kev lag luam tshuaj thiab kev tsim khoom siv tshuaj, trehalose yog qhov tseem ceeb ua tus tiv thaiv lyophilization, protein stabilizer, thiab excipient. Nws tiv thaiv cov tshuaj tiv thaiv kab mob, monoclonal antibodies, enzymes, thiab lwm yam biologics los ntawm denaturation thaum lub sijhawm khov, ziab, thiab khaws cia ntev. Cov kev nce qib tsis ntev los no hauv kev tshawb fawb txog kev tsim tshuaj txuas ntxiv mus lees paub nws lub luag haujlwm hauv kev txhim kho kev ruaj khov thiab cov txiaj ntsig ntawm cov hmoov qhuav nqus pa thiab lwm yam kev xa tshuaj nyuaj. Nws cov biocompatibility thiab kev nyab xeeb profile ua rau nws haum rau cov tshuaj txhaj, qhov ncauj, thiab sab nraud.

Kev lag luam tshuaj pleev ib ce siv trehalose ua cov tshuaj pleev ib ce zoo thiab tiv thaiv daim tawv nqaij. Nws xauv cov dej noo, txo qhov qhuav, thiab pab kho qhov tawv nqaij, ua rau nws yog ib qho khoom xyaw feem ntau hauv cov tshuaj pleev, tshuaj pleev, serums, lub ntsej muag, thiab cov khoom saib xyuas plaub hau. Nws qhov xwm txheej tsis ua rau khaus thiab sib xws nrog ntau hom tawv nqaij txhawb nqa nws siv rau hauv cov tawv nqaij rhiab heev thiab cov mis saib xyuas menyuam yaus.

Kev lag luam thoob ntiaj teb trehalose tab tom loj hlob tas li. Nws kwv yees tias yuav nthuav dav los ntawm USD 201.26 lab hauv xyoo 2026 mus rau USD 262.46 lab los ntawm xyoo 2031, uas sawv cev rau tus nqi loj hlob txhua xyoo ntawm 5.45%. Cov tsav tsheb tseem ceeb suav nrog kev nyiam ntawm cov neeg siv khoom rau cov khoom xyaw ntuj tsim; kev nce qib hauv kev siv tshuab biomanufacturing; thiab kev nthuav dav ntawm daim ntawv thov hauv biopharmaceuticals thiab cov khoom noj muaj txiaj ntsig.

Cov kev tsim kho tshiab tas mus li hauv cov txheej txheem fermentation thiab purification ua rau muaj kev tsim khoom loj, zoo rau ib puag ncig nrog cov nqi txo qis thiab cov pa roj carbon tsawg dua寿光市人民政府. Qhov no txhawb nqa lub hom phiaj kev lag luam kom ruaj khov thaum ua kom muaj kev muab khoom ruaj khov ntawm cov trehalose ntshiab rau kev lag luam thoob ntiaj teb寿光市人民政府.

Thaum cov lag luam tseem niaj hnub muab kev nyab xeeb, zoo, thiab kev ruaj khov tso ua ntej, trehalose sawv tawm ua ib qho khoom xyaw txhim khu kev qha, ua tau zoo uas txuas cov xwm txheej thiab thev naus laus zis. Nws qhov kev sib xyaw ua ke ntawm kev tiv thaiv, kev ruaj khov, thiab kev ua kom noo noo ua kom nws muaj txiaj ntsig zoo rau cov ntawv thov uas twb muaj lawm thaum qhib qhov rooj rau cov cib fim tshiab hauv kev kho mob rov qab, cov khoom noj cog, thiab lwm yam. Nrog kev tshawb fawb thiab kev nce qib thev naus laus zis, trehalose tau teeb tsa kom tswj hwm nws lub luag haujlwm ua ib qho khoom xyaw tseem ceeb uas txhawb nqa tiam tom ntej ntawm cov neeg siv khoom thiab cov khoom lag luam.
