The image shows a lipid bilayer, with the polar heads represented by circles and the hydrophobic tails represented by lines. Arrange the fatty acids in the lipid bilayer to indicate a structure that, when incorporated into a phospholipid, would result in a more fluid membrane with a lower melting point. Be sure to insert the fatty acids into the bilayer in the correct orientation. Not all the fatty acids will be used. {}}{} }}}T MAAAAAAAR
000000000 The steroid lipid cholesterol is a component of membranes. Identify true statements about cholesterol and its role in membrane fluidity. 3 Cholesterol is generally buried in the bilayer, with its planar rings oriented toward the solvent and its hydroxyl group aligned with the fatty acid tails of the bilayer. Cholesterol inhibits the crystallization that would otherwise occur in membranes rich in unsaturated fatty acids. Cholesterol decreases membrane fluidity in areas called rafts, which contain large amounts of sphingolipids and cholesterol. Incorrect Cholesterol increases membrane fluidity in a membrane that otherwise contains mostly long-chain saturated fatty acids.
