Abstract
Animal lipids were separated into glycerides and phospholipids by acetone precipitation and chromatographic methods. It was shown by means of gas-liquid chromatography that the volatile fatty acids comprise 0.68 and 1.28 moles% of the total fatty acids in bovine-muscle and bovine-liver phospholipids, respectively. In muscle phospholipids all the normal acids from C1 to C8, except C7, were detected. In addition, isovaleric acid was present. All the normal acids from C1 to C9, and, in addition, isobutyric, isovaleric and [alpha]-methylbutyric acids, were detected in liver phospholipids.
