Data from Raman spectroscopy, X‐ray diffraction, infrared spectroscopy and differential scanning calorimetry confirm the existence of four solid state phases for trimargarin. Results of the trimargarin investigation are compared to previous results of tristearin and examined in the light of odd vs even chain‐length triglycerides. The conclusion reached is that polymorphic properties of triglycerides result from a balance of three dominant interactions: end‐group planar interactions, lateral hydrocarbon chain interactions and glycerol units intermolecular interactions. This contrasts to a general belief that the end‐group planar interactions dictate physical behavior of lipids.
