A white leghorn hen was given 0.2 mc of 1-C14-cis-2-octenoic acid in one 1.05-g dose, and five eggs laid subsequently were collected. Linoleic acid isolated from the eggs, both as the tetrabromide and by preparative gas-liquid chromatography, was fou

In vitro evidence has been reported for an alternate pathway that involves delta 8 desaturation of n-6 and n-3 polyunsaturated fatty acids (PUFA). The present study was designed to allow detection of delta 8 desaturation in vivo and to provide an est
