Which statement is true about given the topic. 1. Phospholipids. Sphingophospholipids: Sphingosine bonded with 2 Fatty acid molecule via amide linkage and a phosphate group via ester linkage. Glycerophospholipid: 2 Fatty Acid chain, Phosphate and alcohol. 2. Eicosanoids. These are potent regulators of cellular functions. These are derived from arachidic acid further metabolized into three pathways namely cyclooxygenase, lipoxygenase and the CYP450 pathway. 3. Fatty Acid. Fatty acids may also be classified based on the number of carbon atoms where SCFA are fatty acids with 4 to 6 carbons, MCFA with 8 to 10, and LCFA with 12 to 16 carbon atoms. In humans, the simplest fatty acid constructed are the triglycerides composed of fatty acids esterified to a glycerol atom.
