Membrane lipids have fatty acid tails and, like triacylglycerols, their properties are governed by the properties of these tails. Based on what we saw with dietary lipids, which membrane would have more fluid characteristics – the one with more saturated fatty acids or the one with more unsaturated fatty acids? Explain your reasoning. Look at the structure of cholesterol. Cholesterol is a necessary component of biological membranes. What do you think cholesterol would do to the structure of a membrane...

Stage 2: Fatty Acid Degradation to Acetyl CoA (The Fatty Acid Cycle, aka "B-Oxidation")
Stage 2: Fatty Acid Degradation to Acetyl CoA (The Fatty Acid Cycle, aka "B-Oxidation") 1. In the space below, draw the reaction for the activation of palmitic acid, a saturated 16-carbon fatty acid. 2. In the space below, fill in the structure for the reactant acyl CoA and draw all of the products that result from one turn of the fatty acid cycle. Is this reaction an oxidation or a reduction? 3. Besides fatty acid oxidation, glycerol (the other product of triglyceride digestion)...
