Taw qhia

D-lysine yog ib qho amino acid uas belongs rau ib qho ntawm cov amino acids tseem ceeb ntawm tib neeg lub cev. Cov hauv qab no yog cov ncauj lus kom ntxaws txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm D-lysine:

 

Zoo:

D-Lysine yog cov hmoov dawb crystalline uas yog soluble hauv dej thiab dej kub, thiab yuav luag insoluble hauv cawv thiab ethers. Nws muaj ob asymmetric carbon atoms thiab ob enantiomers tam sim no: D-lysine thiab L-lysine. D-lysine yog structurally zoo tib yam rau L-lysine, tab sis lawv spatial configuration yog daim iav-symmetrical.

 

Kev Siv: D-Lysine tuaj yeem siv los ua cov khoom noj khoom haus ntxiv los txhim kho lub cev tiv thaiv kab mob thiab txhawb cov leeg nqaij.

 

Txoj kev:

Muaj ntau txoj hauv kev los npaj D-lysine. Ib txoj hauv kev zoo yog siv cov kab mob me me rau kev tsim khoom fermentation. Los ntawm kev xaiv ib hom kab mob tsim nyog, tsom mus rau txoj hauv kev metabolic ntawm hluavtaws lysine, D-lysine yog tsim los ntawm cov txheej txheem fermentation.

 

Cov ntaub ntawv kev nyab xeeb:

D-lysine yog cov tshuaj muaj kev nyab xeeb thiab tsis muaj tshuaj lom uas tsis muaj kev phiv loj heev. Rau qee pawg neeg, xws li cov poj niam cev xeeb tub, cov poj niam cev xeeb tub, lossis cov neeg muaj kab mob ntev, yuav tsum tau siv los ntawm kws kho mob. Thaum siv D-lysine, cov koob tshuaj tsim nyog thiab kev siv yuav tsum tau ua raws li cov xwm txheej ntawm tus kheej thiab cov lus qhia noj. Nyob rau hauv rooj plaub uas tsis xis nyob los yog ua xua, tsis txhob siv tam sim ntawd thiab sab laj nrog kws kho mob.
