Study Notes
Lactose Intolerance
- Characterized by bloating, gas, abdominal discomfort, and diarrhea
- Occurs when there is insufficient lactase to digest lactose in milk and milk products
Metabolism of Lactose
- Lactose is broken down by the enzyme lactase into glucose and galactose
- Lactose is found in dairy products
Galactosemia
- A rare genetic metabolic disorder that affects an individual's ability to metabolize galactose properly
- Enzymes needed for metabolism of galactose are missing
- Leads to toxic levels of galactose 1-phosphate
