Hydrogen bonding yog tseem ceeb hauv ntau cov txheej txheem tshuaj. Hydrogen bonding yog lub luag hauj lwm rau dej cov kuab tshuaj tshwj xeeb muaj peev xwm. Hydrogen bonds tuav cov kab sib txuas ntxiv ntawm DNA ua ke, thiab lawv yog lub luag haujlwm rau kev txiav txim siab peb-dimensional qauv ntawm folded proteins nrog rau cov enzymes thiab cov tshuaj tiv thaiv.

Thiab cov lus nug yog, vim li cas hydrogen bonds tseem ceeb hauv cellulose molecules?

Hydrogen bonding yog tseem ceeb hauv ib cellulose compound vim lawv pab tswj cov qauv thiab stability ntawm lub cellulose . Cov pab pawg hydroxyl ntawm cov neeg nyob sib ze cellulose daim ntawv chains ntawm hydrogen bonds thiab muab lub zog tensile ntawm cov tebchaw.

Ib yam li ntawd, vim li cas hydrogen bonds tsim ntawm molecules? Hydrogen bonds tsim ntawm cov dej nyob sib ze molecules thaum lub hydrogen ntawm ib qho atom tuaj nruab nrab oxygen atoms ntawm nws tus kheej molecule thiab nws cov neeg zej zog. Qhov no tshwm sim vim qhov hydrogen atom yog attracted rau nws tus kheej oxygen thiab lwm yam oxygen atoms uas tuaj ze txaus.

Ib yam li ntawd, qhov tseem ceeb ntawm hydrogen bonds hauv dej yog dab tsi?

Hydrogen bonds hauv dej muab ntau yam txiaj ntsig zoo rau dej : cohesion (tuav dej molecules ua ke), cov cua kub tshwj xeeb (nqus cua sov thaum tawg, tso cua sov thaum tsim; txo qhov kub hloov pauv), kub kub ntawm vaporization (ntau hydrogen bonds yuav tsum tau tawg thiaj li yuav evaporate dej )

Puas muaj hydrogen bonds nyob qhov twg?

Ib qho piv txwv ntawm a hydrogen daim ntawv cog lus yog pom nruab nrab ntawm cov dej molecules. Nyob rau hauv ib tug discrete dej molecule, muaj ob hydrogen atoms thiab ib tug oxygen atom.
