Incorporation and metabolism of dietary trans isomers of linolenic acid alter the fatty acid profile of rat tissues

2000

To study the influence on lipid metabolism and platelet aggregation of the fatty acid isomerization that occurs during heat treatment, weanling rats were fed for 8 wk a diet enriched with 5% isomerized (experimental group) or normal (control group) canola oil. Geometrical isomers of alpha-linolenic acid representing 0.2 g/100 g of the experimental diet were incorporated into liver, platelets, aorta and heart, at the expense of their cis homologue and of 18:2(n-6). The major isomer, 9c,12c,15t-18:3, was also metabolized to 5c,8c,11c,14c,17t-20:5 and to an unknown compound, found in liver, platelets and aorta, which has been identified tentatively as 7c, 10c,13c,16c,19t-22:5. The greater 20:4…

Modification of the monoaminergic neurotransmitters in frontal cortex and hippocampus by dietary trans alpha linolenic acid in piglets

2002

International audience; The effect of partial isomerization of dietary α-linolenic acid on the monoaminergic neurotransmitters in piglets was studied. After feeding the animals for 14 days with diets containing or not trans α-linolenic acid, neurotransmitters related to the monoaminergic function were quantified in the frontal cortex and in the hippocampus. The partial isomerization of dietary α-linolenic acid resulted in increasing endogenous monoamine levels in the frontal cortex (+55% for dopamine) and was related to a very low incorporation of trans polyunsaturated fatty acids. However, feeding animals with a diet in which the imbalance generated by the isomerization of α-linolenic acid…
