Fatty acid profile (mol%) of epithelium-free mammary fat pads collected from ovariectomized mice fed the control diet (TFA-CON), or the control diet with 5% fat as partially-hydrogenated linseed oil (PH-LIN), partially-hydrogenated safflower oil (PH-SAF), or partially hydrogenated sunflower oil (PH-SUN), or the control diet with 2.7% fat as conjugated linoleic acid (c9,t11/t10,c12-CLA)
