Biological Activity

Arachidic acid is a natural long-chain saturated fatty acid involved in lipid metabolism and cellular membrane structure. As a major component of plant and animal lipids, it participates in fatty acid elongation pathways and influences lipid uptake and membrane fluidity. Saturated fatty acids can modulate metabolic homeostasis and alter downstream inflammatory signaling through the NF-kB pathway.

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 62 mg/mL (198.38 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
FAQ
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).
