Octadecenoic acid (trans-C18:1) is the most abundant form of trans fatty acids in the milk.
The fatty acids which were identified in all the extracts except root bark were hexadecanoic acid (palmitic acid) and 9- octadecenoic acid (oleic acid) in the kernel meal.
Effect of concentrate level on the formation of conjugated linoleic acid and trans- octadecenoic acid by ruminal bacteria with oilseeds in vitro.
The fatty acids detected in the spoilt and healthy fruits are n- Henedecanoic acid and 9- Octadecenoic acid (Z).
To validate the recovery of cis-andtrans-C18:1, which varied widely in relative quantity in clinical samples, standard solutions with varying octadecanoic acids and constant amounts of deuterated lignoceric acid (C24 saturated FA) were calculated for cis-(Figure 2, A) and trans-(Figure 2, B) octadecenoic acid. This showed that recoveries were essentially linear with quantity in the ranges used for analysis (Figure 1, A).
such as the one on the use of octadecenoic acid) contain substantial amounts of (presumably) original experimental data.
Because mammals do not possess [[DELTA].sup.12]-desaturase they cannot convert trans-10 octadecenoic acid to trans-10, cis-12 CLA.
The concentrations of 20 FFAs (lauric acid, myristic acid, pentadecanoic acid, palmitic acid, palmitoleic acid, heptadecanoic acid, stearic acid, oleic acid, octadecenoic acid, linoleic acid, [gamma]-linolenic acid, [alpha]-linoleic acid, arachidic acid, eicosadienoic acid, eicosatrienoic acid, arachidonic acid, eicosapentaenoic acid, docosatetraenoic acid, docosapentaenoic acid, and docohexaenoic acid) were determined in uremic serum or plasma.
An oxylipin corresponding to peak 24, was identified as trihydroxy octadecenoic acid ([C.sub.18][H.sub.33][O.sub.5.sup.-]) with a m/z 329.23328 amu (Rt 18.28 min), determined by its small difference in ppm (0.21262) with the theoretical mass ion; this compound has been previously reported in A.
The sequence begins with the isomerization of LA to cis-9, trans-11 CLA, followed by the hydrogenation of the cis-double bond of the conjugated diene to yield a trans-11 octadecenoic acid (trans-vaccenic acid).
The observed increase in the concentration of 11- Octadecenoic acid and C18:2 trans-10, cis-12 CLA in the meat of the lambs supplemented with fatty acids (Table 5) probably resulted from the higher synthesis of this fatty acid in the rumen.
