Meaning and Definition
A univalent chemical group (−CHO) derived from formic acid, consisting of a carbonyl center bonded to hydrogen.
In organic chemistry, it's the simplest acyl group and the functional group of aldehydes; often found at the beginning of a hydrocarbon chain. In biochemistry, it refers to a specific group in formylated methionine that initiates bacterial protein synthesis.

Common Mistakes When Using “formyl group”
- Incorrect: 'formylgroup' (must be two words or hyphenated: formyl group or formyl-group).
- Incorrect: using 'formyl' as a standalone noun (e.g., 'This molecule has a formyl'); it must specify 'group' or modify another noun (e.g., 'formyl derivative').
FAQ
Frequently Asked Questions
Almost. An aldehyde is a molecule *containing* a formyl group as its functional group. The formyl group (-CHO) is the structural unit itself.
In bacteria, the first amino acid in a new protein chain is a formylated methionine (fMet). The formyl group on the methionine is a key signal for the bacterial translation machinery and is a target for antibiotics.
Not with the naked eye. It is a molecular-scale structure represented in chemical diagrams as -CHO, where C is carbon double-bonded to O (carbonyl) and single-bonded to H.
Yes. Formyl is the acyl group derived from formic acid (HCOOH) by removal of the hydroxyl (-OH) group, leaving H-C=O.
A univalent chemical group (−CHO) derived from formic acid, consisting of a carbonyl center bonded to hydrogen.
Formyl group is usually technical / scientific in register.
Formyl group: in British English it is pronounced /ˈfɔːmɪl ˌɡruːp/, and in American English it is pronounced /ˈfɔːrmɪl ˌɡruːp/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think 'FORMaldehyde' is the simplest aldehyde, and the -YL ending is common for chemical groups (like methyl, ethyl). So, FORM-YL group = the defining group of an aldehyde.
Conceptual Metaphor
A 'flag' or 'starting cap': In biochemistry, the formyl group on methionine acts like a flag marking the start of a bacterial protein assembly line.
