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
