Fatty Acid Research and Health

Volatile acids have been recovered from saponified fats by steamdistillation. Identification of the acids was accomplished by paper chromatography of their hydroxamate derivatives. Analyses of various tissue fats from the rat, dog, and guinea pig, and of human blood lipides showed small amounts of lipide-bound volatile acids in every fat tested. Feeding distilled, acetylated monoglycerides to rats at dietary levels up to 50% increased the lipide-bound, steam-distillable acids in blood but not in tissue fats or carcass fat. The low levels of these acids which were found in tissue fats from a dog fed a standard dog meal were not elevated by feeding a diet containing 25% distilled, acetylated monoglycerides.
