Galactose is a monosaccharide. When it is combined with glucose, the result is disaccharide lactose. The enzyme’s lactose and galactosidase catalyze the hydrolysis of lactose to glucose and galactose. The three key enzymes demonstrate galactose metabolism, which transforms galactose into glucose via a pathway.
Glucose is more stable than galactose, and it is also less vulnerable ...
