Pyrimidine yog ib qho muaj ntxhiab heterocyclic organic compound zoo ib yam li pyridine. Hauv nucleic acids, peb hom nucleobases yog pyrimidine derivatives: cytosine (C), thymine (T), thiab uracil (U).

Hais txog qhov no, pyrimidine hauv biology yog dab tsi?

Pyrimidines yog ib qho ntawm ob tsev neeg tseem ceeb ntawm nitrogen-muaj cov molecules hu ua nitrogenous bases. Purines yog lwm tsev neeg ntawm nitrogenous hauv paus. Pyrimidines tuaj yeem txheeb xyuas los ntawm lawv cov qauv: rau atoms hauv cov duab ntawm lub nplhaib. Lub nplhaib no hu ua a pyrimidine nplhaib.

Tom qab ntawd, lo lus nug yog, qhov kev xaiv twg yog pyrimidine pom hauv DNA? Cov purines, adenine thiab cytosine, loj nrog ob lub nplhaib, thaum lub pyrimidines ua , thymine thiab uracil, me me nrog ib lub nplhaib. Cov lus teb thiab piav qhia: Nqe Lus Nug 1: Qhov tseeb kev xaiv yog F: ob qho tib si B thiab D. Cytosine thiab Thymine yog siv los tsim DNA.

Hauv qhov no, pyrimidine siv rau dab tsi?

Pyrimidines ua haujlwm tseem ceeb hauv tib neeg cov metabolism hauv ribonucleotide hauv paus hauv RNA (uracil thiab cytosine), thiab raws li deoxyribonucleotide hauv DNA (cytosine thiab thymine), thiab txuas los ntawm phosphodiester txuas rau purine nucleotides nyob rau hauv ob-stranded DNA, nyob rau hauv ob qho tib si nucleus thiab thymine. mitochondria cov tsos mob.

Dab tsi yog niam txiv compound hauv pyrimidine nucleotide synthesis?

Tsim Lwm Tus Pyrimidine Nucleotides . UMP yog niam txiv compound hauv synthesis cytidine thiab deoxycytidine phosphates thiab thymidine nucleotides (uas yog deoxyribonucleotides).
