The free fatty acid pattern in blood serum in young spontaneously hypertensive rats.

An investigation on the free fatty acid (FFA) profile in blood serum, using liquid gas chromatography, has been carried out on young (8-9 week-old) spontaneously hypertensive rats (SHR). A significative increase in the level of unsaturated FFA was found in SHR in comparison to their controls. The deviations in the composition of the FFA spectrum found were elevation of the polyunsaturated fatty acids: hexadecanoic acid (C16:2), linoleic acid (C18:2), linolenic acid (C18:3), eicosadienoic acid (C20:2), eicosatrienoic acid (C20:3), eicosapentaenoic acid (C20:5). The differences between FFA profile in SHR and control group can reflect genetically controlled variables.
