| Research Abstract |
In this study a new method for large scale preparation of the fraction of pepsin-processed hen egg white ovalbumin (PHOVA) was developed. PHOVA showed ameliorating effects on lipid metabolism in normal or hyperlipidemic rats. Reductions in abdominal fat accumulation and blood triglyceride concentration were observed. One of the identified peptide in PHOVA directly inhibited the enzyme function of fatty acid synthase and suppressed the fatty acid synthesis in HepG2 hepatocytes. As a result, a new function of ovalbumin on the improvement of lipid metabolism was shown.
