Examine the membrane lipid pictured below and answer the following questions: a. Is this lipid classified as a phospholipid or a glycolipid? Explain your answer in two sentences.b. Is this lipid considered a sphingolipid or a glycerophospholipid? Justify your answer in two sentences. c. What fatty acid chains are used in this lipid? Are they saturated or unsaturated? What functional group enables them to connect to the backbone?
When a substance such as sodium chloride is dissolved in water, the ions become completely surrounded by water molecules, forming structures called hydration spheres. When the sodium salt of a fatty acid is mixed with water, the carboxylate group of the molecule becomes hydrated, but the hydrophobic portion of the molecule is poorly hydrated, if at all. Using a circle to represent the carboxylate group and an attached squiggly line to represent the hydrocarbon chain of a fatty acid, draw a picture of how fatty acids interact with water.
