Cov Ntawv Thovd (+) - tryptophan 丨 cas 153-94-6
1. Kev tshawb fawb thiab kev tshawb fawb biomedical
A. Chirrion Kev Kawm
● Siv hauv kev tshawb fawb hauv kev kawm los sib piv cov kev ua ubiological ntawm l- vs d-tryptophan.
R (+ Tryptophan 丨 cas {{2} Pab rau hauv kev nkag siab enzyme-substrate kev sib txuas lus tshwj xeeb.
B. Tshuaj Kev Loj Hlob
● Pab cov tsev uas muaj zog nyob hauv cov synthesis ntawm peptidomimetics thiab D-amino acid-muaj cov tshuaj vim nws kev tiv taus rau enzymatic degradation.
Qee zaus qee zaus koom nrog kev kho peptive peptides txhawm rau txhim kho kev ruaj khov thiab ib nrab-lub neej.
2. Khoom noj khoom haus thiab chaw kho mob
A. Kev kuaj mob cim
Siv los ua cov qauv siv hauv metabolic thiab khoom noj khoom haus, tshwj xeeb tshaj yog hauv kev txheeb xyuas cov qauv D-kev kuaj xyuas.
● Yuav pab tau microbial profiling txij li qee cov kab mob tsim cov d-tryptophan.
B. Cov Kev Tshawb Fawb Cov Kab Mob B.
● D-Tryptophan yog paub tias yuav tau tsim los ntawm qee cov kab mob probiotic thiab ua haujlwm.
Cov kev tshawb fawb qhia tau qhia txog nws tuaj yeem ua lub luag haujlwm hauv kev kho mob lub cev tsis muaj zog thiab tswj hwm lub plab ntawm cov vajtostasis.
3. Biochemical thiab kev ntsuas kev ntsuas
A. Substrate rau enzymatic cov tshuaj tiv thaiv
● Ua rau substrate lossis inhibitor hauv Enzymatic ua hauj lwm pab cuam tshuam nrog Tryptophanase lossis amino acid oxidase.
Siv nyob rau hauv Kinetic thiab kev tshawb fawb tshuab ntawm amino acid metabolism.
B. Chiral daws teeb meem thiab kev sib cais
● Ua tus qauv lossis tus neeg sawv cev hauv chiral chromatography, tshwj xeeb tshaj yog rau kev sim xaiv cov kab ke hauv cais tawm enantiomers.
4. Kev lag luam thiab khoom siv tshuaj
● ● Siv tshuaj nruab nrab chairal, zoo tshuaj lom neeg, thiab cov lwg me me.
● Ua ib lub luag haujlwm hauv biocatalysis uas yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua si.
5. Kev Tshawb Fawb thiab Kev Tshawb Fawb
● Ib qho cuab yeej muaj txiaj ntsig rau kev tshawb fawb hauv Serochemistry, amino acid metabolism, thiab peptide chemistry.
● Feem ntau siv hauv kev tshawb fawb qauv los soj ntsuam cov qauv-ua haujlwm ntawm cov protein thiab receptors.
Cov txiaj ntsigd (+) - tryptophan 丨 cas 153-94-6
√ Enhanced stability
● Resistant rau enzymatic tawg dua li sau ntawv, ua kom haum rau peptide tshuaj thiab tshawb fawb
√ Txhawb nqa microbiome thiab tiv thaiv kab mob
