Proline Hmoov
Proline (luv ua Pro lossis P), nrog rau cov tshuaj lom neeg C5H9NO2 thiab qhov hnyav molecular ntawm 115.13, yog ib qho cyclic sub amino acid. α- Amino acids, nruab nrab, nrog rau qhov isoelectric point ntawm 6.30, muaj solubility ntau dua hauv dej dua li lwm cov amino acid, thiab tuaj yeem yaj ib ncig ntawm 162g hauv 100g dej ntawm 25 ℃. Yooj yim rau deliquescence tab sis tsis yooj yim rau crystallize, nrog rau saj qab zib. Co cua sov nrog ninhydrin kua tsim cov sib xyaw daj. Thaum nkag mus rau hauv cov saw peptide, hydroxylation tuaj yeem tshwm sim, ua rau muaj kev tsim ntawm 4-hydroxyproline, uas yog ib qho tseem ceeb ntawm cov tsiaj collagen. Hydroxyproline kuj tseem muaj nyob rau hauv ntau yam protein cog, tshwj xeeb tshaj yog cuam tshuam nrog kev tsim ntawm cov phab ntsa cell. Cov nroj tsuag feem ntau muaj kev sib sau ua ke ntawm proline nyob rau hauv ntau yam mob tsis zoo xws li kev qhuav, kub siab, kub qis, thiab salinity. Siv dav hauv kev kho mob, biomaterial, kev lag luam, thiab lwm yam teb.
Muaj peb hom proline:DL proline, L-proline, thiab D-proline. Feem ntau hu ua proline yog L-proline, ib qho amino acid uas tshwm sim hauv ntuj. Thaum sov chav, cov khoom no yog cov siv lead ua ke. Sai sai decompose thaum rhuab mus rau 215-220 ℃. Yaj hauv dej kub thiab ethanol. Qab zib me ntsis thiab hygroscopic. Racemization hauv alkaline kua. [α] D25-86.5 ° (dej), -60.4 ° (5N hydrochloric acid). Muab faib rau ntau yam protein. Ib qho amino acid nrog cov ntsiab lus nruab nrab hauv marine plankton; Nws kuj muaj nyob rau hauv dej hiav txwv, particulate matter, thiab marine sediments.
Proline yog ib qho amino acid tsis tseem ceeb hauv tib neeg lub cev.
Kev Ua Haujlwm thiab Lub Hom Phiaj
Daim ntawv thov hauv kev lag luam tshuaj
Cov tshuaj amino acid. Ib qho ntawm cov khoom siv raw rau kev txhaj tshuaj amino acid sib xyaw. Siv rau kev ntxiv protein tom qab tsis muaj zaub mov zoo, tsis muaj protein txaus, cov kab mob plab hnyuv loj heev, kub hnyiab, thiab phais mob. Tsis muaj cov kev phiv tshuaj lom pom tseeb.
Cov teebmeem ntawm sab hauv
Hauv cov kab mob uas muaj sia nyob, proline tsis yog tsuas yog cov tshuaj osmoregulation zoo tagnrho xwb, tab sis kuj ua haujlwm ua cov tshuaj tiv thaiv rau cov membranes thiab enzymes, nrog rau cov khoom siv dawb radical scavenger, yog li tiv thaiv kev loj hlob ntawm cov nroj tsuag hauv qab kev ntxhov siab osmotic. Rau kev sib sau ua ke ntawm lwm yam tshuaj osmoregulation tseem ceeb hauv vacuoles hauv cov kab mob uas muaj sia nyob potassium ion, proline kuj tseem tuaj yeem ua lub luag haujlwm tswj hwm hauv cytoplasmic osmotic sib npaug.
Cov ntawv thov kev lag luam
Hauv kev lag luam tsim khoom, proline tuaj yeem koom nrog kev tsim cov tshuaj tiv thaiv asymmetric thiab ua haujlwm ua tus catalyst rau hydrogenation, polymerization, thiab dej-mediated reactions. Thaum siv los ua tus catalyst rau cov tshuaj tiv thaiv zoo li no, nws muaj kev ua haujlwm muaj zog thiab zoo stereospecificity.
Cov ntawv thov hauv lwm qhov chaw
1. Proline thiab nws cov derivatives feem ntau yog siv ua cov catalysts symmetric hauv cov tshuaj tiv thaiv organic, nrog rau kev txo qis ntawm CBS thiab cov tshuaj catalytic aldol condensation ntawm proline yog cov piv txwv tseem ceeb.
2. Thaum lub sijhawm ua cawv, cov protein muaj ntau cov proline khi rau polyphenols, uas tuaj yeem tsim cov pa luam yeeb (turbidity).
3. Cov ntaub ntawv raw rau kev tsim cov tshuaj gallstone ester inhibitors.
4. Cov tshuaj tsw qab, uas ua rau muaj suab thaj los ntawm kev sib xyaw ua ke los tsim cov amino hydrogen pawg, tuaj yeem tsim cov tshuaj uas muaj cov tshuaj tsw qab tshwj xeeb.
