Other Pathways of Hexose Metabolism

LEARNING OBJECTIVES
After studying this lesson, students should be able to:

  • Describe the pathways of the metabolism hexoses (other than glucose).
  • Describe the Metabolism of fructose: Metabolic fate of fructose in human body, sorbitol metabolism along with effect of hyperglycemia on sorbitol metabolism.
  • Describe the Metabolism of galactose: Metabolic fate of galactose in body and physiological importance of galactose.
  • Explain the consequences of genetic defects of the  fructose metabolism: essential fructosuria and hereditary fructose intolerance.
  • Explain the consequences of genetic defects of the  fructose and galactose metabolism: galactokinase deficiency and classic galactosemia
