Potassium iodide yog ionic compound uas iodine ions thiab nyiaj ions tuaj yeem tsim daj precipitate silver iodide (thaum pom lub teeb, nws tuaj yeem decompose, nws tuaj yeem siv los ua cov duab thaij duab ceev ceev), nyiaj nitrate tuaj yeem siv los txheeb xyuas qhov muaj ntawm iodine ions. Iodine yog cov khoom xyaw ntawm thyroxine, nws zoo sib xws rau cov tsiaj txhu hauv basal metabolism, nws koom nrog yuav luag tag nrho cov txheej txheem metabolism, cov tsiaj txhu iodine tsis muaj peev xwm ua rau cov thyroid hypertrophy, basal metabolic tus nqi poob, thiab cuam tshuam rau kev loj hlob thiab kev loj hlob.
Cov tub ntxhais hluas cov tsiaj nyeg thiab tsiaj pub ntawm thaj chaw tsis muaj iodine yuav tsum tau ntxiv iodine, iodine yuav tsum tau ua rau cov nyuj loj, cov qoob loo hens yuav tsum nce ntxiv, pub kuj yuav tsum tau ntxiv iodine. Iodine ntawm mis nyuj thiab qe nce nrog kev noj haus iodine.
Raws li cov lus ceeb toom, lub qe qe tuaj yeem txo cov roj cholesterol thiab zoo rau kev noj qab haus huv ntawm cov neeg mob ntshav siab.
Tsis tas li ntawd, thaum lub sij hawm fattening ntawm cov tsiaj, tab sis tsis muaj iodine deficiency, nyob rau hauv thiaj li yuav ua rau cov tsiaj nyeg hypothyroidism muaj zog, txhim khu kev tiv thaiv kev nyuaj siab, tuav lub peev xwm ntau lawm, iodide kuj ntxiv, poov tshuaj iodide raws li iodine qhov chaw ntxiv rau pub, nws. tuaj yeem tiv thaiv cov kab mob iodine deficiency, txhawb kev loj hlob, nce qe ntau lawm thiab kev yug me nyuam thiab txhim kho kev noj zaub mov zoo, tus nqi pub mis feem ntau yog ob peb PPM, vim tias nws tsis ruaj khov, hlau citrate thiab calcium stearate (feem ntau 10%) feem ntau yog ntxiv raws li tus neeg sawv cev tiv thaiv kom nws ruaj khov.
