Dab tsi yog cov reactants thiab cov khoom ntawm cov tshuaj tiv thaiv rau pem hauv ntej (sab laug-rau-txoj cai)?Glucose thiab Fructose yog cov reactants. Sucrose thiab Dej yog cov khoom.
Puas yog cov tshuaj tiv thaiv tom ntej yog cov tshuaj tiv thaiv condensation lossis cov tshuaj tiv thaiv hydrolysis?
Kev faib tawm ntawm cov tshuaj tiv thaiv hydrolysis suav nrog ob qho tib si kev tawm tsam tom ntejuas koom nrog kev sib ntxiv ntawm cov dej rau ib lub molecule kom tawg nws sib nrug los yog rov qab cov tshuaj tiv thaiv cuam tshuam nrog kev tshem tawm cov dej los koom nrog molecules ua ke, termed dehydration synthesis (los yog condensation) (Daim duab 7.7).
Yuav ua li cas ntau yam ntawm cov organic tebchaw sib txawv yog tias cov pa roj carbon muaj xya electrons nyob rau hauv nws lub zog sab nraud tsis yog plaub?
Yuav ua li cas ntau yam ntawm cov organic tebchaw sib txawv yog tias cov pa roj carbon muaj xya electrons hauv nws lub zog sab nraud tsis yog plaub? Nrog xya electrons nyob rau hauv nws lub zog sab nraud, carbon tsis tuaj yeem tsim ob lossis peb npaug nrog lwm cov atoms, kom deb li deb tsawg cov organic tebchaw tuaj yeem tsim.
Kev tawg ntawm polymer cuam tshuam dab tsi?
Polymers tau tawg ua monomers hauv cov txheej txheem hu ua hydrolysis, uas txhais tau tias "siv dej," cov tshuaj tiv thaiv uas siv cov dej molecule thaum lub sij hawm tawg. Thaum cov tshuaj tiv thaiv no, cov polymer tau tawg ua ob yam.
Yog cov tsev me meYuav ua li cas xaiv cov polymers?
Qhov tseem ceeb, monomers yog lub tsev thaiv ntawm polymers, uas yog ntau hom molecules. Monomers-repeating molecular units-yog txuas rau polymers los ntawm covalent bonds.
