Consider olive oil, an oil with a high percentage of fat derived from oleic acid (otherwise known as cis[18:1] fatty acid).
a, Explain why such a structure may allow olive oil to be one of the "healthier" oils?
b, why such a structure may allow olive oil to be a liquid at room temperature, while butter and lard are solid at room temperature?
c, why such a structure may cause olive oil to be prone to oxidative damage upon exposure to air and heat?
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?
Describe the differences between lecithin and cephalin. Draw the structure of a glycerophospholipid containing two molecules of stearic acid and ethanolamine.

- Johann Thudichum, who practiced medicine in London about 100 years ago, also dabbled in lipid chemistry in his spare time. He isolateda variety of lipids from neural tissue and characterized and named many of them. His carefully sealed and labeled vials of isolated lipids were rediscovered many years later.(a) How would you confirm, using techniques not available to Thudichum, that the vials labeled “sphingomyelin” and “cerebroside” actually contain these compounds?(b) How would you distinguish sphingomyelin from phosphatidylcholine by chemical, physical, or enzymatic tests?arrow_forwardD, Since the pK values for aspartic acid are 2.0, 3.9 and 10.0, it follows that the isoelectric (pH) is (A) 3.0 (B) 3.9 (C) 5.9 (D) 6.0arrow_forwardHelparrow_forward
