Which of these statements about the tertiary structure of a polypeptide is(are) untrue? You may select more than one answer. The tertiary structure will be maintained when the solvent is changed from pure water to aqueous acetic acid. O The tertiary structure is determined in part by the formation of disulfide bridges.

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?
