BIOC 385 Exam 2 Questions and Verified Answers (100% Correct Elaborations) Already Passed. What property of albumin protein makes it an ideal biomolecule for transporting fatty acids through the circulatory system? It contains Phe and Tyr residues that serve as binding sites for fatty acids. It contains Asp and Glu residues that serve as binding sites for fatty acids. It is allosterically activated by palmitate binding and inhibited by arachidonate. It contains many alpha helical regions that are known to bind fatty acids. It contains Phe and Tyr residues that serve as binding sites for fatty acids. Partial hydrogenation can result in the formation of_______________. trans double bonds. cis double bonds. ω-3 fatty acids. ω-6 fatty acids. trans double bonds. Pork fat has a melting temperature of 40ºC and flaxseed oil has a melting temperature of -25ºC. What contributes to this ~65ºC difference in melting temperature? Choose the ONE best answer. Animals eat high fatty food, whereas plants use photosynthesis in the hot sun, so the melting temperature differences reflect the lifestyle of the two organisms. Melting temperature reflects the chemistry and physics of hydrogenated fatty acids compared to trans fat and polyunsaturated fats, so flaxseed is liquid and pork fat is not. Pork fat is solid and clumpy, whereas flaxseed oil is liquid, so their melting temperatures reflect the difference in solids over liquids and the amount of enthalpic energy. Pork fat contains 40% palmitate and stearate, whereas flaxseed oil is 53% alpha-linolenate, the difference in average a melting temperature is about 65ºC, so it makes sense. Pork fat contains 40% palmitate and stearate, whereas flaxseed oil is 53% alpha-linolenate, the difference in average a melting temperature is about 65ºC, so it makes sense.
