Tsim ntawm nucleosides

Nucleosides hauv nucleic acids yog tsim los ntawm kev ua kom huv ntawm kev ua kom huv lossis pyrimidide hauv qab nrog cov pob tawb nrog cov roj lossis deoxyribose. Cov pa roj carbon atom (c1) nyob rau hauv tus tav molecule ua ib gyrimidic kev sib khi nrog pyrimidine los tsim lub pyrimidine lossis purine, uas yog hu ua tus ribonuceetoside. Cov pa roj carbon atom (c1) hauv 2-deoxyribose molecule format nrog cov pyrimidine los ntawm pyrimidine los yog pyrimidine lossis purine, uas yog hu ua deoxyribonucleoside. Piv txwv, Adenine txuas nrog rau Ribose los ua Adenine -9- - d-furanosyl nucleoside, uas yog hu ua Adenine nucleoside; Thymine txuas nrog 2'-deoxyribose los ua thymine {}} d-2'}} d-2'}} d-2'-deoxyfuranoside, uas yog hu ua thymidine nucleoside.
