I was at the supermarket the other day shopping for groceries, and I picked up a box of Schtuck Margarine. On the front of the box, it listed “5% trans fats” and on the ingredient list it had “hydrogenated corn oil” listed as the main ingredient. If corn oil is a polyunsaturated vegetable oil with cis- double bonds (only), why is it hydrogenated, and where are the trans fats coming from? Additionally, what is the issue with trans- fats?

For the following molecule, I need to identify several things, but I don't understand how to go about it. a) anomeric carbon b) carbon 1 c) carbon 5 d) which oxygen atoms in a hydroxyl group would point to the right in a Fischer Projection
