✦ Synopsis

Surface tensmn measurements of linoleic acid solutions in 0.1 M sodiumborate buffer pH 10 at 23°C showed that at increasing the hnoleic acid concentration a sharp transition from monomers to mlcelles occurs at 167/aM. At pH 9 and 8 formatmn of acid-soap dimers from monomers starts at 60 btM and 21 /aM respectively. The concentration range at which only monomers exist is therefore markedly reduced. For 13-L-hydroperoxylinolelc acid at pH 10 acid-soap formation still takes place, starting at approx. 220/aM. The total lipid concentratmn at which acid-soap or micelle formatmn starts m mixtures oflinoleic acid and 13-L-hydroperoxyhnolem acid has been determined m relation to the molar ratio of both aclds.
