Qhov sib txawv tseem ceeb ntawm kab thiab cov kab hauv qab yog cov kab hauv kab yog cov micronutrients xav tau los ntawm cov nroj tsuag hauv feeb kom muaj nuj nqis rau cov khoom noj khoom haus, thaum cov ntsiab lus tracer yog radioisotopes ntawm cov ntsiab lus uas muaj txiaj ntsig zoo rau cov nroj tsuag rau kev taug qab txoj hauv kev ntawm cov metabolism. tshuaj.
Cov ntsiab lus yog cov tshuaj lom neeg xav tau los ntawm cov nroj tsuag hauv feeb kom muaj nuj nqis. Cov no txawv ntawm cov ntsiab lus tracer. Feem ntau, cov khoom siv taug qab yog cov khoom siv hluav taws xob hluav taws xob uas tseem ceeb hauv kev kos cov khoom ntawm kev kawm.
Dab tsi yog Cov Ntsiab Lus Dab Tsi?
Cov ntsiab lus yog cov micronutrients cov nroj tsuag xav tau hauv feeb kom muaj nuj nqis rau lawv cov khoom noj. Cov kab ntau tshaj plaws uas cov nroj tsuag xav tau yog tooj liab, zinc, boron, manganese, thiab molybdenum. Txawm li cas los xij, cov kab lus no yuav txawv ntawm ib hom nroj tsuag mus rau lwm qhov. Tsis tas li ntawd, cov tsiaj xav tau qee cov kab mob xws li manganese, iodine, thiab cob alt. Qee yam ntawm cov kab no tseem ceeb rau cov nroj tsuag los muab cov khoom tseem ceeb ntawm lub tsev ntawm cov proteins sib txawv, cov tshuaj hormones, thiab lwm yam txheej txheem.
Qhov tseem ceeb ntawm cov kab ke rau cov nroj tsuag suav nrog cov hauv qab no:
- Txhim kho cov enzymes sib txawv thiab cov tshuaj hormones
- Txoj kev ntawm photosynthesis
- Txhim kho fertility thiab ncua cell
- Kev txhim kho nplooj ntsuab thiab lub zog ntawm cov cell membranes
Thaum siv cov khoom lag luam muaj nyob rau cov nroj tsuag, peb tuaj yeem siv lawv los txo cov kab mob tsis txaus. Hauv daim ntawv thov no, peb tuaj yeem tshuaj tsuag cov kab keeb tshuaj kom maj mam ntub cov nplooj ua ntej dej ntws. Txawm li cas los xij, nws yuav tsum tsis txhob siv rau pob zeb txiv hmab txiv ntoo.
Dab tsi yog Tracer Elements?
Tracer cov ntsiab lus yog radioisotopes ntawm cov ntsiab lus uas muaj txiaj ntsig zoo rau cov nroj tsuag txhawm rau taug qab txoj hauv kev ntawm cov tshuaj tiv thaiv metabolic. Cov ntsiab lus no yuav tsum tau los ntawm cov nroj tsuag hauv feeb kom muaj nuj nqis, feem ntau tsawg dua 0.1 gm / mg ntawm qhov hnyav qhuav ntawm cov nroj tsuag.
Ib qho isotopic tracer yog ib qho hluav taws xob atom uas tuaj yeem ntes tau hauv cov khoom siv hauv tshuaj lom neeg, lom neeg, lossis lub cev, thiab peb tuaj yeem siv cov ntsiab lus no los cim cov khoom ntawm kev kawm uas ua rau nws yooj yim los soj ntsuam kev nce qib cov ntaub ntawv los ntawm qhov system los yog txiav txim siab faib cov khoom ntawm kev kawm. Qee qhov piv txwv ntawm hom xov tooj cua no muaj xws li antimony-124, bromine-82, iodine-125, iodine-131, iridium-192, thiab scandium-46.
Dab tsi yog qhov zoo sib xws ntawm Txoj Cai thiab Cov Ntsiab Lus Tracer?
- Cov ntsiab lus thiab cov kab cim kab yog cov tshuaj tseem ceeb hauv cov nroj tsuag biology.
- Nroj tsuag xav tau ob qho tib si kab thiab kab hauv cov khoom me me.
Dab tsi yog qhov txawv ntawm Kab thiab Cov Ntsiab Lus Tracer?
Qhov sib txawv tseem ceeb ntawm kab thiab cov kab hauv qab yog cov kab hauv kab yog cov micronutrients xav tau los ntawm cov nroj tsuag hauv feeb kom muaj nuj nqis rau cov khoom noj khoom haus, thaum cov ntsiab lus tracer yog radioisotopes ntawm cov ntsiab lus uas muaj txiaj ntsig zoo rau cov nroj tsuag rau kev taug qab txoj hauv kev ntawm cov metabolism. tshuaj tiv thaiv. Tooj liab, zinc, boron, manganese, thiab molybdenum yog cov piv txwv ntawm cov kab mob thaum antimony-124, bromine-82, iodine-125, iodine-131, iridium-192, thiab scandium-46 yog cov piv txwv ntawm cov ntsiab lus tracer.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov kab thiab cov kab hauv qab hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Trace vs Tracer Elements
Cov ntsiab lus yog cov khoom siv tshuaj uas xav tau los ntawm cov nroj tsuag hauv feeb kom muaj nuj nqis, thaum cov ntsiab lus tracer yog cov tshuaj lom neeg muaj zog tseem ceeb hauv kev kos cov khoom ntawm kev kawm. Qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob tracer yog tias cov kab mob yog cov micronutrients xav tau los ntawm cov nroj tsuag hauv feeb kom muaj nuj nqis rau cov zaub mov noj, thaum cov ntsiab lus tracer yog radioisotopes ntawm cov ntsiab lus uas muaj txiaj ntsig zoo rau cov nroj tsuag rau kev taug kev ntawm cov tshuaj tiv thaiv metabolic.
