- Consider the following fatty acids: CH3-(CH₂) 12-C-OH Myristic Acid CH3-(CH2)4-CH=CH-CH₂-CH=CH-CH2- 0 B) Which fatty acid listed above would have the lower melting point? Linoleic Acid A) What type of fatty acid is Linoleic Acid (Saturated, Monounsaturated or Polyunsaturated)? C) Draw the structure of a triacylglycerol that contains two molecules of linoleic acid and one molecule of myristic acid D) True or False: As the number of carbons in a saturated fatty acid increases, the melting point decreases. E) True or False: As the number of double bonds in an unsaturated fatty increases the melting point decreases.

Is the fatty acid saturated, monounsaturated, or polyunsaturated? d. Is it most likely to be solid or liquid at room temperature? e. Would it be soluble in water?arrow_forward4. The ester you drew in Question #1 has a melting point range of 32-35 °C. The methyl ester of mono-unsaturated palmitoleic acid (IUPAC name: hexadec-9enoic acid) has a considerably lower melting point range: -0.5-+0.5 °C. a) Explain what it means for a fatty acid to the "mono-unsaturated." b) Illustrate your explanation by drawing the structure of the methyl ester of octadec-11-enoic acid.
