The same won't happen in Galactokinase deficiency (another form of galactosemia) because the galactose won't be phosphorylated to Galactose 1-P, so it can return to the blood stream and won't accumulate on the liver.
a agree with you, for remember. Galactose is asugar body if body cant utilize it it can cause hypoglycemia and as Dhiegocx saied its accumulate in liver because 1st enzyme is fine its converted galactose into galactose1P but 2nd enzyme is not working so its cant enter another pathways or it cant get out from hepatocyte then accumulate...accumulate then lead to liver damage
. and as we know out Back up at fasting LIVER gluconeogenesis and beta-oxidation cant run so hypoglycemia.
