Product Detail

Khoom cim npe

Proline (ua luv li Pro lossis P), nrog rau cov tshuaj formula C5H9NO2 thiab molecular hnyav ntawm 115.13, yog ib tug cyclic sub amino acid.α- Amino acids, nruab nrab, nrog ib qho isoelectric point ntawm 6.30, muaj solubility hauv dej ntau dua li lwm cov amino acid, thiab tuaj yeem yaj nyob ib ncig ntawm 162g hauv 100g dej ntawm 25 ℃.Yooj yim rau deliquescence tab sis tsis yooj yim rau crystallize, nrog rau qab zib saj.Co cua sov nrog ninhydrin tov generates daj compounds.Thaum nkag mus rau cov saw peptide, hydroxylation tuaj yeem tshwm sim, ua rau tsim ntawm 4-hydroxyproline, uas yog ib qho tseem ceeb ntawm cov tsiaj collagen.Hydroxyproline kuj tseem muaj nyob rau hauv ntau cov nroj tsuag cov protein, tshwj xeeb tshaj yog muaj feem xyuam rau kev tsim cov phab ntsa ntawm tes.Nroj tsuag feem ntau muaj kev cuam tshuam loj ntawm proline nyob rau hauv ntau yam kev mob tshwm sim xws li drought, kub kub, tsis tshua muaj kub, thiab salinity.Siv dav hauv kev kho mob, biomaterial, industrial, thiab lwm yam.

Muaj peb hom proline:DL proline, L-proline, thiab D-proline.Feem ntau hu ua proline yog L-proline, ib txwm tshwm sim amino acid.Nyob rau hauv chav tsev kub, cov khoom no yog ib tug columnar siv lead ua.Sai sai decompose thaum rhuab mus rau 215-220 ℃.Soluble hauv dej kub thiab ethanol.Me ntsis qab zib thiab hygroscopic.Racemization nyob rau hauv alkaline kua.[α] D25-86.5 ° (dej), -60.4 ° (5N hydrochloric acid).Muab faib rau hauv ntau yam proteins.Ib qho amino acid nrog cov ntsiab lus nruab nrab hauv marine plankton;Nws kuj tseem muaj nyob hauv dej hiav txwv, cov teeb meem me me, thiab cov sediments marine.

Proline yog ib qho tsis tseem ceeb amino acid nyob rau hauv tib neeg lub cev.

Muaj nuj nqi thiab lub hom phiaj

Daim ntawv thov hauv kev lag luam kws tshuaj

Amino acid tshuaj.Ib qho ntawm cov khoom siv raw rau compound amino acid infusion.Siv rau cov protein ntxiv tom qab kev noj zaub mov tsis txaus, tsis muaj protein ntau, kab mob plab hnyuv loj, kub hnyiab, thiab cov txheej txheem phais.Tsis muaj kev phiv tshuaj lom neeg pom tseeb.

Cov teebmeem intrabiological

Hauv cov kab mob uas muaj sia nyob, proline tsis yog tsuas yog ib qho zoo tshaj plaws osmoregulation tshuaj, tab sis kuj yog ib qho khoom siv tiv thaiv rau daim nyias nyias thiab enzymes, nrog rau cov dawb radical scavenger, yog li tiv thaiv cov nroj tsuag kev loj hlob nyob rau hauv osmotic kev nyuaj siab.Rau kev sib sau ntawm lwm cov tshuaj osmoregulation tseem ceeb hauv vacuoles hauv cov kab mob poov tshuaj ion, proline tuaj yeem ua lub luag haujlwm tswj hwm hauv cytoplasmic osmotic tshuav nyiaj li cas.

Cov ntawv thov kev lag luam

Hauv kev lag luam synthesis, proline tuaj yeem koom nrog inducing asymmetric reactions thiab ua lub catalyst rau hydrogenation, polymerization, thiab dej mediated tshua.Thaum siv los ua ib qho catalyst rau cov tshuaj tiv thaiv zoo li no, nws muaj zog ua haujlwm thiab zoo stereospecificity.

Cov ntawv thov hauv lwm qhov chaw

1. Proline thiab nws cov derivatives feem ntau yog siv los ua symmetric catalysts hauv cov tshuaj tiv thaiv organic, nrog rau kev txo qis ntawm CBS thiab catalytic aldol condensation cov tshuaj tiv thaiv ntawm proline yog cov piv txwv tseem ceeb.

2. Thaum lub sij hawm brewing, cov protein yog nplua nuj nyob rau hauv proline khi rau polyphenols, uas yuav ua rau haze (turbidity).

3. Cov ntaub ntawv nyoos rau kev sib txuas ntawm gallstone ester inhibitors.

4. Cov tshuaj tsw qab, uas ua rau muaj suab thaj los ntawm cov cua sov los tsim cov amino hydrogen pawg, tuaj yeem tsim cov tshuaj tsw qab tshwj xeeb.
