galactokinase

Galactokinase is an enzyme crucial for metabolizing galactose, a sugar found in milk. In a hereditary condition called galactosemia, this enzyme is inactive, preventing the conversion of galactose-1-phosphate to glucose-1-phosphate. This metabolic block leads to the accumulation of galactose-1-phosphate, causing symptoms like cataracts and liver damage. Galactosemia can be managed by eliminating milk and milk products from the diet, especially in infancy, to prevent severe health issues. The regulation of enzymes like galactokinase is a key aspect of cellular metabolism, allowing cells to adapt to changing dietary conditions and hormonal balances.12
