Outline of Final Research Achievements

Until present, it was very few information of trans and cis-trans mixed type fatty acid for human healthy influence. However, to evaluate health influence, it is necessary that we understand the level of daily intake from various food. Our results as below; 1) trans and cis-trans isomer of linoleic acid and the linolenate were synthesized and identified, which were applied the highly precise analysis of their fatty acids, 2) it was clarified their level in various kinds of food and a mother's milk sample, 3) it was observed the phenomenon forming at the time of cooking heating.
It is convinced that these results become able to provide useful knowledge to evaluate of health impact having trans and cis-trans essential fatty acid isomers.
