In a second series of experiments, Hanczyc et al. [52] found that the myristoleic acid vesicles could be induced to grow by addition of fatty acid to the medium, presumably by incorporating fatty acid molecules into the membrane, rather than by fusion of vesicles. If the resulting suspension of large vesicles was then filtered through a polycarbonate filter having pores 0.2 pm in diameter, the larger vesicles underwent a kind of shear-induced division to produce smaller vesicles. This process could be repeated several times (Fig. 5). [Pg.14]

Linoleic (>30%), oleic (>18%), and Unolenic (2-12%) acids are the most predominant unsaturated fatty acids present (9). Lemon, lime, and citron oils contain the highest amount of linolenic acid. In addition, very small amounts of myr-istoleic acid (C14 l) in polar lipids fraction, myristoleic (C14 l) and palmitoleic (C16 l) acids in diacylglycerols fraction, and myristoleic (C14 l) and eicosaenoic (C20 l) acids in triacylglycerols fraction of citms seed oil were also identified (39). [Pg.1420]

Since animals are able to desaturate up to, but not including, the C12 position, products of the n-7 (palmitoleic acid) and n-9 (oleic acid) families and the lesser-known n-5 myristoleic (9-C14 ln-5) family are interesting but not dietary essential. However, n-6 and n-3 fatty acids must be provided in food or feed to enable... [Pg.2315]

Strain D S5 oxidized unsaturated but not saturated fatty acids. The relative activities were in the following order oleic > palmitoleic > arachidonic > linoleic > linolenic > y-linolenic > myristoleic acids. [Pg.216]

The strain DS5 system produced more keto product from palmitoleic and oleic acids and more hydroxy product from myristoleic, linoleic, and a- and y-linolenic acids. The reason for fliis preference is not clear. Among die 18-carbon unsaturated fatty acids, an additional double bond in either side of die C-10 position lowers the enzyme hydration activity. A hterature search revealed diat all microbial hydratases hydrate oleic and linoleic acids at the C-10 position (Fig. 2). Therefore, die positional specificity of microbial hydratases might be universal. [Pg.217]
