Synthetic glycerides containing stearic and oleic acids have been prepared and incorporated into the diets of rats. The stearic acid in the glycerides has been shown to be very indigestible. It is better utilized when fed as mixed glycerides than when fed as tristearin mixed with triolein. The possibility of selective utilization of fat acids has been indicated. Support is given to the hypothesis that either hydrolysis of glycerides or ester interchange precedes absorption.
