"galactose" 的定义和意义

What is "galactose"?

Galactose is a type of sugar, classified as a monosaccharide, that is less commonly found in nature compared to glucose and fructose. It naturally occurs in dairy products like milk and yogurt, as well as in certain fruits and vegetables. Galactose is less sweet than glucose and fructose and plays a role in making lactose, the sugar found in milk. Once ingested, galactose is broken down in the body and changed into glucose, which serves as a primary source of energy for cells.
