The positional distribution of isovaleric acid in natural cetacean triglycerides has been studied using proton magnetic resonance with lanthanide shift reagents. Twenty‐nine samples of melon, jaw, and blubber triglycerides from 13 genera in the Delphinidae, Phocoenidae, and Monodontidae families were examined. Isovaleric acid was found esterified only at the 1,3‐positions in the monoisovaleroyl and diisovaleroyl triglycerides of these animals.
