The effects of fish oils with different degrees of hardening on the biosynthesis of L-ascorbic acid were investigated using rats fed diets containing as unhardened fish oil (FO), 4 kinds of hardened fish oil (HFO), and soybean oil (SO) as the control at the 20% (wt/wt) level. Urinary excretion and concentration of L-ascorbic acid in the liver and serum were measured.<BR>The urinary excretion of L-ascorbic acid from the FO and HFO groups increased significantly regardless of the degree of hardening of the oil. In general, the liver and serum levels of acid increased in the FO and HFO groups with duration of the feeding period.<BR>From these results, it follows that the biosynthesis of L-ascorbate in rats is stimulated not only by dietary HFO but by dietary FO as well.
