Elaidic acid was given to rats either as free acid or triglyceride (trielaidin or mixed glycerides transesterified with elaidic acid). The intestinal mucosa and lymph triglycerides were isolated and their structure determined by pancreatic lipase. The elaidic acid level was determined by GLC using capillary columns. Results showed a marked tendency for elaidic acid to be located at the external positions of the triglyceride molecule beginning with the lymph. The results are discussed in relation to the absorption process and triglyceride synthesis.
