| Outline of Final Research Achievements |
In this study, we aimed to verify the ameliorating effects of the pepsin and heat-processed ovalbumin fraction (PHOVA) and the fatty acid synthase (FAS) inhibiting peptide (WTSSN) contained in PHOVA on sugar and lipid metabolism. The feeding of PHOVA to the obese and type II diabetes model mice remarkably suppressed the blood glucose concentration, showing an ameliorating effect of carbohydrate metabolism. The feeding of PHOVA to chickens reduced the blood and hepatic triacylglycerol concentration, showing an ameliorating effect of lipid metabolism. WTSSN and polyunsaturated fatty acid (PUFA) suppressed triacylglycerol accumulation in HepG2 hepatocytes. Moreover, ω6 PUFAs showed the strongest inhibitory effect on FAS activity.
