glycolipid
Very LowHighly Technical / Scientific
Definition
Meaning
A lipid (fat) molecule attached to a carbohydrate (sugar) chain, found in cell membranes.
A complex molecule consisting of a lipid and a carbohydrate, crucial for cell recognition, signaling, and structural integrity in the membranes of all living organisms, particularly abundant in the nervous system.
Linguistics
Semantic Notes
Exclusively used in biochemistry, cell biology, and related fields. It is a compound word formed from 'glyco-' (sugar) and 'lipid' (fat).

Memory Aids
Mnemonic
Think: 'GLYCOse' (sugar) + 'LIPID' (fat) = a fat with a sugar hat, sitting on the cell's surface.
Conceptual Metaphor
A cellular 'name tag' or 'antenna' that identifies the cell and receives chemical signals.

Common Pitfalls
Translation Traps (for Russian speakers)
- Direct calque 'гликолипид' is correct and standard.
- Avoid separating into 'глико-липид' with a hyphen in formal writing.
- Do not confuse with 'гликопротеин' (glycoprotein), which has a protein core.
Common Mistakes
- Mispronouncing as 'glyco-lip-id' with equal stress on all syllables (correct stress is on 'lip').
- Misspelling as 'glycolypid' or 'glycolicpid'.
- Using it in a non-scientific context where it would be incomprehensible.

Frequently Asked Questions
No, it is a highly specialized scientific term with very low frequency outside of technical contexts in biochemistry and medicine.
No, 'glycolipid' is exclusively a noun. There is no verb form.
Glycolipids primarily function in cell recognition, cell signaling, and maintaining the stability and structure of cell membranes.
Gangliosides, which are abundant in the nervous system, are a major type of glycolipid.
