Daim ntawv thov
1.Thymine yog ib qho khoom siv nitrogenous hauv cov nucleic acid ntawm DNA.
2.A nucleobase pom nyob rau hauv deoxyribonucleic acids (DNA).
3.Ua ib qho nruab nrab rau Zidovudine.
4.As cov khoom siv rau Thymidine
Ib qho pyrimidine hauv paus cais tawm ntawm thymus.Nws yog soluble hauv dej kub thiab tuaj yeem decomposed ntawm 335-337 ° C.Lub thymine (T) nyob rau hauv ib tug strand ntawm DNA molecule yog ua ke nrog adenine (A) nyob rau hauv lwm yam strand los tsim ob hydrogen bonds, uas yog ib tug ntawm cov tseem ceeb zog rau lub stability ntawm DNA ob helix qauv.
Nws yog ib qho tseem ceeb nruab nrab ntawm cov synthesis ntawm cov tshuaj tiv thaiv AIDS AZT, DDT thiab lwm yam tshuaj.Cov ntaub ntawv raw khoom: glacial acetic acid, butyl acetate, methanol, methyl methacrylate, urea, hydrochloric acid, ethanol.Kuj tseem tuaj yeem ua ke los ntawm cov txheej txheem tshuaj.Siv hauv kev tsim tshuaj.Thymine yog ib qho ntawm cov hauv paus hauv deoxyribonucleic acid.Nws tuaj yeem ua ke nrog deoxyribose los ua ib qho deoxyribonucleoside ntawm thymine, cov khoom uas hu ua trifluorothymidine deoxyribonucleoside tom qab hydrogen ntawm 5-txoj hauj lwm methyl pawg yog hloov los ntawm fluorine.
