1. Extensive treatment with phospholipase A2 of a right-side-out, sealed plasma membrane vesicle preparation from a human fibroblast cell line hydrolyzes a fraction of the lipids in each phospholipid class (see table below). Note that phospholipase A2 hydrolyzes the ester linkage on the fatty acyl chain at the 2-position of a phosphoglyceride. Assuming that the accessible substrate lipids are present on both leaflets (monolayers) of the plasma membrane, calculate the phospholipid composition of each leaflet. Report the calculated percentage of...

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...
