Question 1
Which of the following is NOT an example of a common sterol?
◦ estrogen
◦ stearic acid
◦ vitamin D
◦ corticosteroid hormones
Question 2
Which of the following statements explains the chemical significance of the double bond and its placement in fatty acids?
◦ The double bond can form an infinite number of different configurations that dictate how the molecule is shaped in nature.
◦ The two isomers of conjugated linoleic acid are both eighteen carbons long and have two double bonds. One isomer has been found to reduce tumor growth and the other to reduce triacylglycerol synthesis, which can reduce body fat.
◦ The cis-double bond, as in oleic and linoleic acid, forms a bend in the molecule, so it fills more space, which makes all trans-fats bad and nonessential.
◦ Humans can consume enough of these compounds and benefit significantly from the two molecules known as conjugated linoleic acid.
