Positional analysis of isovaleroyl triglycerides using proton magnetic resonance with Eu(fod)3 and Pr(fod)3 shift reagents: II. Cetacean triglycerides.

Abstract

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.
