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.
