Meaning and Definition
A chemical compound consisting of arabinose (a sugar) linked to another molecule, often used to refer to nucleosides where arabinose replaces ribose or deoxyribose.
In biochemistry and pharmacology, arabinosides are analogs of natural nucleosides where the sugar arabinose substitutes for ribose or deoxyribose. They often function as antimetabolites, interfering with DNA synthesis, and are used in antiviral and anticancer therapies (e.g., cytarabine).

FAQ
Frequently Asked Questions
No, it is a highly specialised technical term used almost exclusively in biochemistry, pharmacology, and related sciences.
An arabinoside contains the sugar arabinose, while a riboside contains ribose. This small structural difference significantly alters the biological activity of the molecule.
Yes, Cytarabine (ara-C) is a critically important chemotherapy drug used to treat certain leukemias. It is a cytosine arabinoside.
The differences reflect broader patterns: British English often uses a short 'i' (/ɪ/) in the middle syllable and stress on 'bin', while American English often uses a long 'o' (/oʊ/) and stress on 'no'.
A chemical compound consisting of arabinose (a sugar) linked to another molecule, often used to refer to nucleosides where arabinose replaces ribose or deoxyribose.
