ABO cov pab pawg ntshav koom nrog ob antigens thiab ob qhov tshuaj tiv thaiv pom hauv tib neeg cov ntshav. Ob tug antigens yog antigen A thiab antigen B .. Ob qhov tshuaj tiv thaiv kab mob yog antibody A thiab antibody B . Cov antigens muaj nyob ntawm cov qe ntshav liab thiab cov tshuaj tiv thaiv kab mob hauv cov ntshav.
Raws li, qhov sib txawv ntawm A thiab B antigen yog dab tsi?
Cov qhov sib txawv ntawm A thiab B . ntshav antigens yog ib qho qab zib nkaus xwb thaum kawg antigen . Hom A antigen muaj lub davhlau ya nyob twg N-acetylgalactosamine whereas hom B ua antigen muaj lub davhlau ya nyob twg galactose.
Kuj Paub, hom macromolecule twg yog A thiab B antigens yog tsim los ntawm? Hom kev lom neeg macromolecules
| Biological macromolecule | Tsev thaiv | Piv txwv |
|---|---|---|
| Cov lipid | Fatty acids thiab glycerol | Cov rog, phospholipids, waxes, roj, roj, steroids |
| Cov protein | Cov amino acids | Keratin (pom hauv cov plaub hau thiab rau tes), cov tshuaj hormones, enzymes, tshuaj tiv thaiv kab mob |
| Nucleic acids | Nucleotides | DNA, RNA |
Kuj paub, antigens dab tsi hauv ntshav hom A?
ntshav pawg A- muaj A antigens ntawm cov qe ntshav liab nrog rau B cov tshuaj tiv thaiv kab mob hauv cov ntshav. ntshav pawg B - muaj B antigens nrog anti-A antibodies hauv cov ntshav. ntshav pawg O-tsis muaj antigens, tab sis ob qho anti-A thiab anti- B cov tshuaj tiv thaiv kab mob hauv cov ntshav.
Dab tsi antigens muaj nyob hauv ntshav hom B?
B. 'B' hom ntshav yog tus yam ntxwv ntawm qhov muaj 'B'-hom antigens hauv cov qe ntshav liab thiab los ntawm 'A'-type antibodies in the ntshav . Raws li qhov xwm txheej ntawm 'A' lossis 'O'-hom ntshav, tus neeg uas muaj ntshav' B 'tej zaum yuav yog Rh+ lossis Rh -, nyob ntawm seb puas muaj Rh protein nyob rau hauv cov qe ntshav liab.
