cytidine monophosphate
Very LowSpecialist/Scientific
Definition
Meaning
A nucleotide consisting of cytosine, ribose, and one phosphate group; a fundamental building block of RNA.
In biochemistry, it is a crucial monomeric unit in RNA synthesis and a key intermediate in nucleotide metabolism and energy transfer within cells.
Linguistics
Semantic Notes
Always used in singular form; refers to a specific molecular entity. The abbreviation 'CMP' is common in technical contexts.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling of related general terms (e.g., 'synthesise' vs. 'synthesize') may follow regional conventions.
Connotations
Identically technical and precise in both dialects.
Frequency
Extremely rare outside specific scientific fields in both regions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'monophosphate' word-for-word as 'монофосфат' without the context of 'цитидин'; the correct full term is 'цитидинмонофосфат' (ЦМФ).
Common Mistakes
- Misspelling as 'cytidin monophosphate' (dropping the 'e').
- Confusing it with cytidine diphosphate (CDP) or triphosphate (CTP).

FAQ
Frequently Asked Questions
Yes, in biochemical nomenclature, 'cytidine monophosphate' and 'cytidylic acid' are synonyms, both referring to CMP.
No. DNA contains deoxycytidine monophosphate (dCMP), which lacks a hydroxyl group on the ribose sugar compared to the ribose in CMP found in RNA.
It indicates the presence of a single phosphate group esterified to the sugar moiety of the cytidine nucleoside.
CMP is a central intermediate. It can be phosphorylated to form cytidine di- and triphosphates (CDP, CTP) for RNA synthesis, or it can be deaminated to form uridine monophosphate (UMP), linking the pyrimidine nucleotide pathways.
