Biological Activity
Petroselinic acid is a naturally occurring monounsaturated fatty acid and positional isomer of oleic acid that serves as a structural lipid constituent and biochemical intermediate. It incorporates into cellular membrane lipids to modulate membrane fluidity and lipid signaling pathways, while demonstrating anti-inflammatory properties by attenuating inflammatory mediator production. Petroselinic acid also acts as a lipid substrate in microbial bioprocesses for synthesizing novel sophorolipid biosurfactants. [1]

| Solvent | Solubility & Note |
|---|---|
| DMSO |
56 mg/mL
(198.25 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.) |
| Water | 56 mg/mL |
| Ethanol | 56 mg/mL |
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
