| Outline of Final Research Achievements |
We analyze the regulation of sugar and lipid metabolism after intake of high sugar diet. We did not prove the hypothesis that the increased hepatic store of glycogen initiated the biosynthesis of fatty acid after fasting and refeeding. Glycerol 3-phosphate dehydrogenase 1 (GPD1) catalyzes the conversion process between sugar and lipid metabolism. In GPD1 null mouse, contribution of lipid oxidation as a fuel source for exercise is increased, and gluconeogenesis from glycogenic amino acids is also increased after fasting. Finally, we demonstrated that the blood level of any phosphatidylcholine (PC), such as PC(16:0/16:1) and PC(16:0/18:1), was increased after intake of high sugar diet, suggesting that these two PCs would be good biomarkers for intake of high sugar diet.
