cytidylic acid
Very LowTechnical/Scientific
Definition
Meaning
A nucleotide, specifically the phosphorylated form of cytidine, consisting of cytosine, ribose, and a phosphate group.
It functions as a monomeric unit in RNA (ribonucleic acid) and is involved in various biochemical processes, including RNA synthesis and metabolism. It exists in two main isomeric forms, 2'-cytidylic acid and 3'-cytidylic acid, depending on the phosphate group's position on the ribose sugar.

Examples
By Part of Speech
adjective
British English
- The cytidylyl transfer reaction was crucial.
- Cytidylic acid residues were analysed.
American English
- The cytidylyltransferase enzyme was purified.
- Cytidylic acid metabolism was studied.
Examples
By CEFR Level
- Cytidylic acid is a word used by scientists.
- In biology class, we learned that cytidylic acid is part of RNA.
- Cytidylic acid, often abbreviated as CMP, is one of the four main ribonucleotides found in RNA molecules.
- The research demonstrated that the enzyme's active site preferentially binds cytidylic acid over other nucleotide monophosphates during transcription.

Memory Aids
Mnemonic
Think: CYTI(dylic) - like CITRUS (C for Cytosine) + DYNAMIC (for the energy in its phosphate bond) + ACID.
Conceptual Metaphor
A building block or letter in the genetic alphabet (RNA).

Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод «цитидиловая кислота» является точным. Сокращение «ЦМФ» (цитидинмонофосфат) — прямой аналог CMP. Важно не путать с цитидином (cytidine), у которого нет фосфатной группы.
Common Mistakes
- Misspelling as 'cytidilic acid' or 'cytidylicacid' (omitting the space).
- Confusing it with cytidine (the nucleoside without the phosphate).
- Using it in a non-scientific context where it would be incomprehensible.

FAQ
Frequently Asked Questions
Cytidine is a nucleoside (cytosine + ribose sugar). Cytidylic acid (CMP) is a nucleotide, meaning it is cytidine with an added phosphate group.
It is found as a free nucleotide in the cytoplasm and, more importantly, as a monomer incorporated into RNA strands.
No. The deoxyribonucleotide equivalent in DNA is deoxycytidylic acid (dCMP), which contains deoxyribose sugar instead of ribose.
In British English: sigh-ti-DILL-ik. In American English: sigh-tə-DILL-ik. The emphasis is on the third syllable.
