Phospholipids are the primary lipids constituting the cellular membrane architecture, typically composed of a glycerol backbone, two FA chains, a phosphate group and a head group. The head group includes different types such ... | 5 | Evidence #3 and #5 together provide the answer. Phosphatidylethanolamine (PE) is distinguished from phosphatidylcholine (PC) by the Raman band at 760 cm⁻¹ originating from the ethanolamine group in PE (Evidence #3). Additionally, Evidence #5 mentions that the bands at 722 and 1088 cm⁻¹, corresponding to ν(P–O) and symm... |
