Recently, consumption of trans fatty acids has been linked to high blood cholesterol levels and increased risk of heart disease. The food industry has responded by decreasing use of "trans fats." Consider the following questions: (a) How do the structures and transition temperatures of trans, cis, and saturated fatty acids differ, and what are the effects on membrane fluidity? (b) Are trans fatty acids abundant in nature? (c) The major source of trans fats is hydrogenated oils. (The trans fats are produced by a side reaction during the hydrogenation process.) Why has the food industry used synthetically produced hydrogenated oils?
