Low temperature partial alcoholysis of triglycerides

G. V. Marinetti

University of Rochester School of Medicine and Dentistry, Department of Biochemistry, Rochester, New York

Egg triglycerides chromatographed on silicic acid are eluted in a skew curve in which fatty acid composition varies.

The triglycerides were cleaved by sodium methoxide in chloroform-methanol at 0°C to yield diglycerides (11.3%) and monoglycerides (17.5% of original triglycerides) after 3 min. Complete cleavage to fatty acid methyl esters and glycerol was obtained at 18 min at 0°C or 5 min at room temperature.

Supplementary key words alcoholysis • triglycerides • low temperature • partial methanolysis • asymmetric elution curves
