(a) Interpretation: The category to which the given lipid structure belongs should be identified. Concept Introduction: Lipids are a type of chemical substances which is not soluble in water but soluble in non-polar solvents. Lipids are of two type simple lipids and complex lipids. Simple lipids are those where Glycerol attached with fatty acid. In complex lipids there are two major lipids i, e, Phospholipids and Glycolipids.
