Dej ? Dej yog ib qho inorganic molecule nrog cov khoom tshwj xeeb uas ua rau nws yog ib qho tseem ceeb tshaj plaws rau cov khoom muaj sia. Hauv dej molecule ( H2O ), cov hydrogen thiab oxygen atoms daim ntawv cog lus kom cov nqi hluav taws xob tsis sib xws.
Xav txog qhov no, cov ntsiab lus ntawm lub neej yog dab tsi?
Ntawm ntau hom organic tebchaw, plaub pawg loj muaj nyob hauv txhua yam muaj sia: carbohydrates , lipids , cov proteins , thiab nucleic acids.
Tsis tas li ntawd, vim li cas cov ntsiab lus tseem ceeb rau cov tsiaj muaj sia? Tshuaj Cov tshuaj hauv Tej yam muaj sia Biochemical tshuaj sib xyaw ua kom cov hlwb thiab lwm cov qauv ntawm kab mob thiab ua lub neej txheej txheem. Carbon yog lub hauv paus ntawm tag nrho cov biochemical tshuaj sib xyaw , yog li carbon tseem ceeb rau lub neej nyob ntiaj teb. Tsis muaj carbon, lub neej raws li peb paub nws yuav tsis muaj nyob.
Ua li no, cov ntsiab lus thiab cov ntsiab lus dab tsi uas muaj nyob hauv cov khoom muaj sia?
Rau qhov feem ntau ntawm cov khoom muaj sia nyob yog carbon , hydrogen , oxygen , nitrogen , phosphorus , thiab leej faj . Atoms ntawm cov ntsiab lus no ua ke thiab tsim ntau txhiab tus loj molecules. Cov molecules loj no tsim cov qauv ntawm cov hlwb thiab ua ntau yam txheej txheem tseem ceeb rau lub neej.
Yuav ua li cas 4 organic tebchaw yog carbon pom nyob rau hauv?
Cov pa roj carbon monoxide yog qhov tshwj xeeb ntawm lwm cov ntsiab lus vim tias nws tuaj yeem sib txuas hauv txoj kev tsis muaj kev txwv nrog cov ntsiab lus xws li hydrogen, oxygen, nitrogen, sulfur thiab lwm yam carbon atoms. Txhua yam nyob ib leeg xav tau plaub hom organic tebchaw kom ciaj sia - carbohydrates , lipids , nucleic acids thiab cov proteins.

Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
