Siv:
Cov tshuaj reagents lom, tshuaj ntau, pab pawg sulfhydryl (-SH) muaj nyob hauv cov molecule tuaj yeem tsoo cov saw disulfide (-SS) uas txuas cov mucin peptide saw hauv cov hnoos qeev. Mucin dhau los ua peptide saw ntawm cov molecules me me, uas txo cov viscosity ntawm cov hnoos qeev; nws tseem tuaj yeem ua txhaum DNA cov fibers hauv cov hnoos qeev, yog li nws tuaj yeem tsis tsuas yog yaj cov hnoos qeev dawb tab sis kuj hnoos qeev. Nws tau siv hauv kev tshawb fawb biochemical, ua phlegm solubilizer thiab tshuaj tua kab rau acetaminophen lom hauv tshuaj. Cov txheej txheem ntawm kev ua yog tias cov pab pawg sulfhydryl muaj nyob hauv cov khoom tsim qauv tuaj yeem ua txhaum cov disulfide bond hauv mucin polypeptide saw hauv cov hnoos qeev, ua kom cov mucin, txo cov viscosity ntawm cov hnoos qeev, thiab ua kom nws liquefied thiab yooj yim hnoos. Nws yog qhov tsim nyog rau cov neeg mob uas muaj kab mob ua pa hnyav thiab mob hnyav uas nws hnoos qeev thiab nyuaj rau hnoos, nrog rau cov hnoos qeev txhaws txhaws ntau uas ua rau muaj tsos mob hnyav vim nyuaj rau nqus.
Khaws:
hauv qhov chaw qhuav, huv thiab qhov cua. Txhawm rau zam kev ua qias tuaj, nws raug txwv tsis pub tso cov khoom no ua ke nrog cov tshuaj lom lossis tshuaj lom. Hnub tas sij hawm yog ob xyoos.
