The lingual lipase in gastric aspirates from premature infants was found to be partially stereospecific for sn ‐3 esters of synthetic enantiometric triacylglycerols containing 18∶1 and 16∶0. The sn ‐3 ester was hydrolyzed about 4 times faster than the acid at the sn ‐1 position with no difference in rates between 18∶1 and 16∶0. The sn ‐2 was also hydrolyzed to some extent.
