3-hydroxyUndecanoicacid is a hydroxylated fatty acid that has been found in S. algae, LPS extracted from clinical isolates of B. catarrhalis, and methyl-branched poly(3-hydroxyalkanoate) (PHA) polymers produced by P. flava isolated from oil-contaminated soil. It inhibits sodium current in axons dissected from mantles of giant squid (D. bleekeri) with an ED50 value of 0.46 mM.
3-HydroxyUndecanoicAcid Methyl Ester, a hydroxylated fatty acid methyl ester, is present in methyl-branched poly(3-hydroxyalkanoate) (PHA) polymers synthesized by P. oleovorans, P. putida, and D. tsuruhatensis [Matreya, LLC. Catalog No. 1730].
