Nucleoside #

They are denoted as such I suppose due to the importance of Nucleotides, in that they just lack their phosphate group.

DNA uses thymine (T) and RNA additionally uses uracil (U), both pyrimidines:

• There are concentrative and equilibrative nucleoside transporters; CNT(1-3)/ENT(1-4). I believe they are both unidirectional, but more commonly the former is shown to be unidirectional, while ENT is bidirectional.
• There is a to-be-identified vesicular transporter.

Ribonucleoside #

After being bound to Ribose, Adenosine, Guanosine, 5-MThyluridine, Uridine, and Cytidine.

Deoxyribonucleoside #

Deoxyadenosine (dA), Deoxyguanosine (dG), thymidine (dT), Deoxyuridine (dU), deoxycytidine (dC).
