Interpretive Summary:

Technical Abstract: Symmetrical disaturated triacylglycerols (TAGs) are important components providing functionality to interesterified fat blends and structurally modified oils, while the presence of non-symmetrical TAGs of the SSU configuration [S = stearic acid and U = unsaturated (oleic (O), linoleic (L), or linolenic (Ln)) fatty acids] can significantly change melting point and solid fat index profiles. To characterize the physical properties of non- symmetrical disaturated TAGs, a new synthesis was developed to prepare multi-gram quantities of SSL, SSO and SSLn, all with purities of >98%. Silver resin chromatography and Ag- HPLC were used to isolate and analyze the non-symmetrical TAGs, respectively.
