Determination of the glyceride structure of fats. glyceride structure of fats with unusual fatty acid compositions

Abstract Five fats containing less common fatty acids, nutmeg butter (myristic), rapeseed oil (erucic, eicosenoic), peanut oil (arachidic, behenic, lignoceric), tung oil (eleostearic), and coriander seed oil (petroselinic) were oxidized, and the oxidized esterified glycerides were analyzed by gas‐liquid chromatography (GLC). The values obtained are compared with those calculated from lipase hydrolysis data. Although there was a general over‐all agreement between the compositions calculated from lipase hydrolysis data and that obtained by GLC analysis of the oxidized glycerides, there were some discrepancies that exceeded the range of experimental error.
