Subject: Trans Fats vs. Saturated Fats

In class the other day, we were discussing lipids.  My teacher mentioned that 
unsaturated fats are unsaturated they're not stuffed with hydrogen (basically), 
unlike saturated fats which ARE stuffed with hydrogen.  The process of 
hydrogenation is taking an unsaturated fat and stuffing hydrogens on there.  
Why then do [hydrogenated fats] become worse for you, because wouldn't they 
then just be saturated fats?  Why do they become trans fats?
