title: Fatty acid compositions of triacylglycerols and phospholipids in hen liver lipid before and after sexual maturity.
abstract: Changes in fatty acid composition of triacylglycerols and phospholipids of the hen liver lipid on coming into egg production were described. Of the major fatty acids of triacylglycerols, a high content of oleate and low content of stearate and polyenoic acids were observed in the hen liver at all ages (97 to 167 days of age). In contrast, high stearate and polyenoic acids were present in the liver phospholipids at all ages. The oleate content in triacylglycerols was twice that of phospholipids. Triacylglycerols of the hen liver were more unsaturated than phospholipids throughout the experiment. The triacylglycerols of the control and estrogenized male chicks were also more unsaturated than the phospholipids. The distribution patterns of carbon-18 fatty acids (stearate, oleate, and linoleate) of triacylglycerols and phospholipids in liver lipid were examined. Both females and males showed similar distribution patterns of carbon-18 fatty acids of the triacylglycerols. In the phospholipids, all birds also showed similar distribution patterns, but these patterns were distinctly different from those of the triacylglycerols.
