nucleoside
This term describes a specific molecular building block in biochemistry. It is distinguished from a nucleotide by the absence of a phosphate group. In a laboratory or clinical setting, the term is frequently used when discussing antiviral drugs or DNA synthesis, where the focus is on the base-sugar pairing before phosphorylation occurs.
As a technical chemical term, it follows standard English countability rules for molecules. It is used as a countable noun when referring to specific types of nucleosides (e.g., adenosine or cytidine) or individual molecules in a chemical reaction.
Meanings
A compound consisting of a nitrogenous base linked to a sugar, serving as the precursor to a nucleotide.
The synthesis of the nucleoside was monitored using high-performance liquid chromatography.
Examples
A nucleoside consists of a nitrogenous base and a pentose sugar.
A nucleoside consists of a nitrogenous base and a pentose sugar.
The researcher analyzed the purity of the synthetic nucleoside.
Many antiviral drugs are designed as nucleoside analogues.
The enzyme catalyzes the phosphorylation of the nucleoside.
The enzyme catalyzes the phosphorylation of the nucleoside.
I need to double check the structure of this specific nucleoside.
The study focuses on how the nucleoside interacts with the receptor.
