Ordering Information

Biological Activity

10-Undecenoic acid is an unsaturated fatty acid that functions as a natural fungistatic agent. It inhibits fungal cell morphogenesis, notably suppressing the dimorphic transition from yeast to hyphal forms and preventing biofilm formation in Candida albicans. By impairing cellular membrane integrity and disrupting morphogenesis-related pathways, 10-undecenoic acid exhibits broad-spectrum antifungal activity useful in antimicrobial formulations.

Solvent Solubility & Note
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).
