Kev coj kev sim siv Benedict's, Iodine, Biuret, thiab Sudan IV kev daws teeb meem. Txheeb xyuas qhov zoo tswj xeem tshuaj tiv thaiv rau txhua tus macromolecule . Siv cov txiaj ntsig ntawm qhov paub xeem cov tshuaj tiv thaiv los txheeb xyuas cov macromolecules . Siv cov txiaj ntsig ntawm qhov paub xeem kev tshwm sim los txheeb xyuas cov macromolecules nyob rau hauv tsis paub.
Ntawm no, koj siv dab tsi los kuaj cov macromolecule monosaccharide?
Kuaj rau lub xub ntiag ntawm qab zib, uas yog monosaccharides , los ntawm siv lub Benedict xeem . ? Kuaj rau lub xub ntiag ntawm starch, a polysaccharide , los ntawm siv Lub Lugol's iodine xeem.
macromolecule dab tsi yog Benedict qhov kev tshuaj ntsuam xyuas rau? qab zib
Tom qab ntawd, lo lus nug yog, vim li cas peb thiaj kuaj macromolecules?
Txhua hom macromolecule muaj ib tug yam ntxwv qauv thiab muaj nuj nqi nyob rau hauv cov kab mob. Koj ua tau siv koj txoj kev paub txog cov qauv ntawm txhua tus macromolecule ua kuaj nyob rau hauv lub chaw kuaj mob uas kuaj pom muaj lossis tsis muaj cov pab pawg ua haujlwm tseem ceeb lossis tag nrho cov yam ntxwv ntawm ntau yam khoom.
Ib qho piv txwv ntawm macromolecule yog dab tsi?
Cov piv txwv ntawm Macromolecule Polymers muaj cov subunits, hu ua mers, uas yog covalently txuas rau cov qauv loj. Proteins, DNA, RNA, thiab yas yog tag nrho cov macromolecules . Muaj ntau cov carbohydrates thiab lipids cov macromolecules . Carbon nanotubes yog ib qho piv txwv ntawm macromolecule uas tsis yog khoom siv roj ntsha.

Vim li cas Ames kuaj rau mutagens siv los kuaj cov carcinogens MCAT?
Cov lus nug nug tus neeg kuaj xyuas kom piav qhia tias vim li cas Ames kuaj rau mutagens tuaj yeem siv los kuaj cov carcinogens. Hauv kev xeem Ames, cov tshuaj uas ua rau muaj kev hloov pauv hauv Salmonella kuaj kab mob tuaj yeem yog cov carcinogens, vim tias lawv hloov pauv DNA thiab DNA hloov pauv tuaj yeem ua rau mob qog noj ntshav (B)
Cov khoom siv kuaj dej yog dab tsi?
Cov khoom siv kuaj dej muaj ib lub hom phiaj - txhawm rau txheeb xyuas cov kab mob hauv koj cov dej, yog li koj tuaj yeem siv cov kev ntsuas tsim nyog los xyuas kom koj muaj kev nyab xeeb. Cov khoom siv kuaj dej kuaj pom muaj ntau yam kab mob, xws li hlau, txhuas, nitrate, nitrite, alkalinity, tshuaj tua kab, hardness, kab mob thiab lwm yam
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Lub npe ntawm cov enzyme uas kuaj pom hauv qhov kev kuaj pom zoo catalase yog dab tsi?
Catalase Test- Ntsiab Cai, Siv, Txheej Txheem, Txhais Lus Txhais nrog ceev faj. Qhov kev sim no qhia pom tias muaj catalase, ib qho enzyme uas ua rau cov pa tawm ntawm cov pa oxygen los ntawm hydrogen peroxide (H2O2)
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
