Siv Amino acid tshuaj.
Kev tshawb nrhiav hauv vitro Ntau yam d-amino acids, xws li D-serine, D-aspartic acid (D-Asp), thiab D-glutamic acid (D-Glu) yog dav pom nyob rau hauv cov tsiaj nyeg xws li tib neeg thiab tam sim no xav tias yog cov neeg sib tw ntawm tshiab physiologically active tshuaj thiab/los yog biomarkers. D-[Asp/Glu] (4 mg/mL) inhibits IgE binding (75%) rau txiv laum huab xeeb thaum D-Glu, D-Asp tsis muaj inhibitory nyhuv. IgE yog tshwj xeeb rau D-[Asp/Glu] thiab tej zaum yuav muaj peev xwm tshem tawm IgE lossis txo IgE khi rau txiv laum huab xeeb.
Hauv vivo kawm D-glutamic acid yog tam sim no them nyiaj mloog raws li ib tug modulator ntawm neuronal kis tau tus mob thiab hormonal secretion. Nws tsuas yog metabolized los ntawm D-aspartate oxidase hauv cov tsiaj. Tom qab txhaj tshuaj intraperitoneal, L-glutamate yog catabolized ntawm a-ketoglutarate, thaum D-glutamate hloov mus rau n-pyrrolidone carboxylic acid. Cov pa roj carbon 2 ntawm D- thiab L-glutamate hloov dua siab tshiab hauv cecum rau methyl carbon ntawm acetate. Ob leeg nas lub siab thiab lub raum catalyze hloov dua siab tshiab ntawm D-glutamic acid rau n-pyrrolidone carboxylic acid.

Taw qhia

D-glutenate, tseem hu ua D-glutamic acid los yog sodium D-glutamate, yog ib txwm tshwm sim amino acid nrog ntau yam khoom tseem ceeb thiab siv.

 

Cov khoom tseem ceeb ntawm D-gluten yog raws li hauv qab no:

Me ntsis saj: D-gluten yog ib qho umami enhancer uas txhim khu lub umami saj ntawm cov zaub mov thiab txhim khu cov tsw ntawm cov zaub mov.

Khoom noj khoom haus ntxiv: D-gluten yog ib qho ntawm cov amino acids tseem ceeb rau tib neeg lub cev thiab ua lub luag haujlwm tseem ceeb hauv kev saib xyuas tib neeg kev noj qab haus huv.

Chemically ruaj khov: D-glunine yog qhov ruaj khov nyob rau hauv acidic tej yam kev mob thiab tuaj yeem tswj cov txheeb ze ruaj khov nyob rau hauv qhov kub thiab txias.

 

Kev siv D-Gluten Acid:

Kev tshawb fawb biochemical: D-glutamic acid yog siv dav hauv kev tshawb fawb biochemical thiab kev sim los kawm txog nws cov tshuaj biochemical thiab cov txheej txheem metabolic hauv cov kab mob muaj sia.

 

Txoj kev npaj ntawm D-gluten yog tsuas yog tau los ntawm microbial fermentation los yog tshuaj synthesis. Microbial fermentation ntau lawm tam sim no yog txoj kev npaj tseem ceeb, siv qee hom los tsim cov D-glutamic acid ntau los ntawm fermentation. Kev siv tshuaj lom neeg feem ntau siv cov khoom siv hluavtaws thiab cov tshuaj tiv thaiv tshwj xeeb los ua ke D-gluten acid.

 

Cov ntaub ntawv kev nyab xeeb ntawm D-Gluten: Feem ntau, D-Gluten muaj kev nyab xeeb nyob rau hauv cov xwm txheej ntawm kev siv thiab khaws cia. Tsis tas li ntawd, rau qee cov neeg, xws li cov menyuam mos thiab cov poj niam cev xeeb tub, lossis cov neeg uas muaj glutamate rhiab heev, nws yuav tsim nyog siv los yog zam D-glutamate nyob rau hauv ib nrab.
