Galactose loading test has long been used as one of so-called liver function tests. However, the significance and mechanism (s) of the test have not been clarified from the viewpoint of liver “functions”. Galactose metabolism has been known to be inhibited by NADH at the site of epimerization from UDP-galactose to UDP-glucose. Therefore, galactose metabolism would be affected by the level of plasma FFA concentration as in the case of glucose metabolism in the liver. In order to study this possibility, the relationship between galactose and lipid metabolism was examined in human beings.
