A hydrogen daim ntawv cog lus yog electromagnetic attraction ntawm polar molecules nyob rau hauv uas hydrogen yog khi rau lub atom loj, xws li oxygen lossis nitrogen. Qhov no tsis yog kev sib koom ntawm electrons, zoo li hauv covalent daim ntawv cog lus . Hloov chaw, qhov no yog qhov kev nyiam ntawm qhov zoo thiab qhov tsis zoo ntawm cov atom raug nqi.

Tsis tas li, qhov twg hydrogen bonds tshwm sim hauv biology?

Hydrogen bonds tshwm sim nyob rau hauv inorganic molecules, xws li dej, thiab organic molecules, xws li DNA thiab proteins. Ob qho tib si txuas ntxiv ntawm DNA yog tuav ua ke los ntawm hydrogen bonds ntawm cov nucleotides ntxiv (A&T, C&G).

Ib yam li ntawd, vim li cas hydrogen bonding tseem ceeb hauv biology? 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.

Tsis tas li ntawd, piv txwv li hydrogen bond yog dab tsi?

hydrogen daim ntawv cog lus . npe. Lub ntsiab txhais ntawm hydrogen daim ntawv cog lus yog tshuaj daim ntawv cog lus nruab nrab ntawm hydrogen atom thiab electronegative atom. Ib piv txwv ntawm hydrogen daim ntawv cog lus yog dej molecules kev sib raug zoo ua ke nyob rau hauv daim ntawv ntawm dej khov.

Yuav ua li cas yog hydrogen bond tsim?

A hydrogen daim ntawv cog lus yog tsim thaum qhov zoo kawg ntawm ib lub molecule yog attracted rau qhov tsis zoo kawg ntawm lwm tus. Lub tswvyim zoo ib yam li magnetic attraction qhov twg opposite ncej nyiam. Qhov no ua rau hydrogen ib qho hluav taws xob zoo atom vim nws muaj qhov tsis txaus ntawm electrons.
