Triglycerides were isolated from the liver, plasma, kidney, adrenals, testes (one animal), heart, pancreas, rumen wall, muscle, intestines, and perineal, intestinal and subscapular adipose tissues from four adult sheep. The fatty acid composition of each was determined by gas chromatography. The distribution of fatty acids among positions 1, 2 and 3 of the glycerol moeity of the triglycerides was determined by a stereospecific analysis procedure. In the adipose tissue triglycerides, saturated components predominated in position 1 and unsaturated C 18 fatty acids were found largely in position 2; position 3 was occupied mainly by C 18 saturated and unsaturated fatty acids. The highest concentration of trans‐ fatty acids was in position 3. The triglycerides obtained from the other tissues had similar structures to this except that in some, in particular plasma and liver triglycerides, there was a comparatively high concentration of palmitic acid in position 2.
