Maphunziro a in vitro Ma d-amino acid osiyanasiyana, monga D-serine, D-aspartic acid (D-Asp), ndi D-glutamic acid (D-Glu) amapezeka kwambiri mwa nyama zoyamwitsa kuphatikiza anthu ndipo tsopano akuganiziridwa kuti ndi omwe angasankhe. zinthu zatsopano zokhudzana ndi thupi komanso / kapena zolembera. D-[Asp/Glu] (4 mg/mL) imaletsa IgE kumanga (75%) ku mtedza pamene D-Glu, D-Asp ilibe cholepheretsa. IgE ndi yachindunji ya D--[Asp/Glu] ndipo ikhoza kukhala ndi kuthekera kochotsa IgE kapena kuchepetsa IgE kumangiriza ku zosagwirizana ndi mtedza.
Kuphunzira mu vivo D-glutamic acid pakadali pano imayang'aniridwa ngati modulator ya kufala kwa neuronal komanso kutulutsa kwa mahomoni. Imapangidwa ndi D-aspartate oxidase mu nyama zoyamwitsa. Pambuyo jekeseni wa intraperitoneal, L-glutamate imasinthidwa kudzera pa-ketoglutarate, pamene D-glutamate imasinthidwa kukhala n-pyrrolidone carboxylic acid. Mpweya 2 wa D- ndi L-glutamate umasinthidwa mu cecum kukhala methyl carbon of acetate. Chiwindi cha makoswe ndi impso zonse zimathandizira kutembenuka kwa D-glutamic acid kukhala n-pyrrolidone carboxylic acid.

Mawu Oyamba

D-glutenate, yomwe imadziwikanso kuti D-glutamic acid kapena sodium D-glutamate, ndi amino acid yomwe imapezeka mwachilengedwe yokhala ndi katundu wosiyanasiyana komanso ntchito.

 

Zofunikira zazikulu za D-gluten ndi izi:

Kukoma pang'ono: D-gluten ndi umami wowonjezera kukoma komwe kumawonjezera kukoma kwa umami ndikuwonjezera kukoma kwa zakudya.

Zakudya zowonjezera: D-gluten ndi imodzi mwama amino acid ofunikira m'thupi la munthu ndipo imagwira ntchito yofunika kwambiri posunga thanzi la munthu.

Kukhazikika kwamankhwala: D-glunine imakhala yokhazikika pansi pa mikhalidwe ya acidic ndipo imathanso kukhalabe yokhazikika pakatentha kwambiri.

 

Kugwiritsa ntchito D-Gluten Acid:

Kafukufuku wam'chilengedwe: D-glutamic acid imagwiritsidwa ntchito kwambiri pakufufuza zamankhwala ndi zoyeserera kuti aphunzire momwe amagwirira ntchito komanso njira zama metabolic m'zamoyo.

 

Kukonzekera njira ya D-gilateni makamaka akamagwira tizilombo nayonso mphamvu kapena kaphatikizidwe mankhwala. Kupanga kwa Microbial fermentation ndiyo njira yayikulu yokonzekera, pogwiritsa ntchito mitundu ina kupanga kuchuluka kwa D-glutamic acid kudzera mu nayonso mphamvu. Kaphatikizidwe ka Chemical nthawi zambiri amagwiritsa ntchito zida zopangira komanso momwe zimachitikira kuti apange D-gluten acid.

 

Chidziwitso cha Chitetezo cha D-Gluten: Nthawi zambiri, D-Gluten ndi yotetezeka pansi pamikhalidwe yogwiritsidwa ntchito moyenera ndikusungidwa. Kuonjezera apo, kwa anthu ena, monga makanda ndi amayi apakati, kapena omwe ali ndi mphamvu za glutamate, zingakhale zoyenera kugwiritsa ntchito kapena kupewa D-glutamate moyenera.
