Saturated fatty acids are so named because they are saturated with (a) hydrogen (b) water (c) hydroxyl groups (d) glycerol (e) double bonds
Figure 2.17 Fatty acids. Double bonds in the tails are highlighted in red. A. The tail of stearic acid is fully saturated with hydrogen atoms. B. Linoleic acid, with two double bonds, is unsaturated. The first double bond occurs at the sixth carbon from the end of the tail, so linoleic acid is called an omega-6 fatty acid. Omega-6 and C. omega-3 fatty acids are essential fatty acids, which means your body does not make them and they must come from food. D. The hydrogen atoms around the double bond in oleic acid are on the same side of the tail. Most other naturally occurring unsaturated fatty acids have these cis bonds. E. Hydrogenation creates abundant trans bonds, with hydrogen atoms on opposite sides of the tail. Figure It Out: Are the double bonds in linolenic acid cis or trans?
Fatty acids in phospholipids and triacylglycerols interact with one another by (a) disulfide bridges (b) van der Waals interactions (c) covalent bonds (d) hydrogen bonds (e) fatty acids do not interact with one another
Unlike saturated fatty acids, the tails of unsaturated fatty acids incorporate one or more _______. a. phosphate groups b. glycerols c. double bonds d. single bonds
Which of the following statements is true of fatty acids? Group of answer choices The more carbon atoms and nitrogen atoms present in a fatty acid, the shorter the fatty acid is. The more hydrogen atoms attached to carbon atoms, the more saturated a fatty acid is. All fatty acids are solid at room temperature. All fatty acids have only double bonds. All fatty acids have the same chain length.
Which of the following best describes the fatty acid 20:3n-4? A. There are 20 carbons plus three carboxyl group in the molecule. B. It is a saturated fatty acid. C. The molecule is an ω4 fatty acid. D. 20:3Δ4,7,10,13. E. It is a monounsaturated fatty acid
Which of the following statements about trans-fatty acids is/are FALSE? a.Healthier than saturated FA. b.Formed from the hydrogenation of C=C. c.May be present in butter substitutes. d.Properties are similar to saturated FA.
Which of the following statements about trans-fatty acids is/are FALSE? A. Healthier than saturated FA. B. May be present in butter substitutes. C. Properties are similar to saturated FA. D. Formed from the hydrogenation of C=C.
Fatty acids are esterified into mono-, di-, or triglycerides by attaching to: Sterol Cholesterol Glycerol Sodium chloride Omega-3 fatty acids have which of the following? At least 3 double bonds A 3-carbon backbone A double bond 3 carbons from the end of the chain At least 3 fatty acid molecules linked by omega bonds
Which of the following statements regarding trans fatty acids is FALSE? Trans fatty acids increase the shelf-life of processed foods. Trans fatty acids were saturated fatty acids prior to hydrogenation. A diet that is rich in trans fatty acids increases the risk of heart disease, and therefore trans fatty acids in foods must be labeled. Trans fatty acids are a byproduct of hydrogenating fats.

Which of the following is not a type of lipid? A) lipoproteins B) glycerides C) enzymes D) steroids E) unsaturated fatty acids
