Draw a triacylglycerol (triglyceride) made from glycerol, myristic acid [CH₂(CH₂)2COOH], palmitic acid [CH₂(CH₂)₁4COOH], and oleic acid [CH₂(CH₂)₂CH=CH(CH₂),COOH(cis)] . Place palmitic acid at the middle position. Cis/trans isometry is graded; it may help to draw hydrogen atoms associated with the carbon atoms of the double bond. Incorrect What did I do wrong?
Which of the statements are true? Unsaturated fats have higher melting points than saturated fats. Fats that contain more saturated fatty acid residues than unsaturated fatty acid residues are more likely to be solid at room temperature. Triacylglycerols (triglycerides) are carboxylic acids. Unsaturated fats are more likely than saturated fats to be liquid at room temperature. Triacylglycerols (triglycerides) contain ester bonds.
Arrange the fatty acids from highest melting point to lowest melting point. - CH3(CH2)10COOH - CH3(CH2)7CH=CH(CH2)7COOH - CH3(CH2)4(CH=CHCH2)4(CH2)2COOH - CH3(CH2)14COOH Select the statements about fatty acid melting points that are true. - A saturated fatty acid with a greater molar mass has a higher melting point than a saturated fatty acid with a lower molar mass. - A saturated fatty acid with a greater molar mass has a lower melting point than a saturated fatty acid with a lower molar mass. - A saturated fatty acid has a higher melting point than an unsaturated fatty acid. - A saturated fatty acid has a lower melting point than an unsaturated fatty acid.

21. Two fatty acids found in rapeseed oil are behenic acid and erucic acid. Both contain the same number (22) of carbon atoms. Behenic acid is saturated and erucic acid is monounsaturated. The abbreviated structural formula of erucic acid is CH, (CH,),CH=CH-(CH2)11COOH. (a) Deduce the abbreviated structural formula for behenic acid 4 b) Explain why the melting point of erucic acid is lower than that of behenic acid 22. A cell membrane can vary in terms of how "fluid" or "flexible" it is. Describe if you would expect each of the following changes to make a particular membrane more fluid or more rigid. Explain your choices. a) An increase in the cholesterol content b) An increase in the fraction of unsaturated fatty acyl tails in the membrane phospholipids.
