    What's the difference between deoxyribonucleotide and deoxyribonucleoside?
    I've learnt that:

    nucleoside = base + sugar

    nucleotide = base + sugar + phosphate

    Also, deoxyribonucleoside triphosphate has obviously got a phosphate group (triphosphate), so why is it referred to as deoxyribonucleoSIDE?

    This may be a bit confusing, but a massive thanks in advance

    Nucleosides appear a bit more in biological chemistry. Adenosine (Adenine without the phosphate part) can be oxidised and then phosphorylated 3 times to give ATP.
    Nucleotides are restricted to purines/pyrimidines to form DNA/mRNA/tRNA/rRNA in genetics
