Galactokinase is an enzyme that catalyzes the first step in the metabolism of galactose by phosphorylating it to galactose-1-phosphate, playing a crucial role in energy production and cellular metabolism. Deficiency in galactokinase can lead to galactosemia, a condition characterized by the accumulation of galactose in the blood, potentially causing cataracts and other complications.

Energy production is the process of generating energy from primary sources such as fossil fuels, nuclear, and renewable resources to meet human consumption needs. It involves complex systems and technologies that convert these sources into usable electricity or fuel, impacting economic, environmental, and social dimensions globally.

Cellular metabolism comprises all chemical reactions within cells that enable them to maintain life, grow, reproduce, and respond to their environments. It is divided into catabolic pathways that break down molecules to release energy and anabolic pathways that build complex molecules from simpler ones.

Galactosemia is a rare genetic metabolic disorder characterized by the inability to properly metabolize galactose, leading to toxic accumulation that can cause serious health issues if untreated. Early diagnosis and dietary management, primarily by eliminating lactose and galactose from the diet, are crucial to prevent complications such as liver damage, intellectual disability, and cataracts.

Cataracts are a clouding of the eye's natural lens, leading to a decrease in vision, and are a common cause of blindness worldwide. They can be treated effectively with surgery, which involves replacing the cloudy lens with a clear artificial lens.
