HUMAN NUTRITION

Detailed explanation-1: -After absorption from the alimentary canal, much of the fructose and almost all of the galactose is rapidly converted into glucose in the liver.

Detailed explanation-2: -Galactose can be converted to glucose-6-P, after which it can be used for glycogen synthesis; or it can be oxidized further to form PYR or acetyl-CoA for additional energy generation or fatty acid synthesis. Galactose is initially phosphorylated by galactokinase to form galactose-1-phosphate (galactose-1-P).

Detailed explanation-3: -Galactose is a simple sugar that is normally transformed in the liver before being used up as energy. This sugar is quite abundant in human diets and helps in a number of functions. Because galactose is a precursor to glucose production, it is an important energy-providing nutrient.

Detailed explanation-4: -Galactose is a monosaccharide. When combined with glucose (another monosaccharide) through a condensation reaction, the result is a disaccharide called lactose.
