WebThe glucose moiety of lactose is metabolised to lactic acid by glycolysis. Lactococci produce 4 mol L-lactate per mol lactose. Most other lactic acid bacteria transport lactose into the cell as lactose using a permease. These organisms hydrolyse lactose to glucose and galactose using a beta-galactosidase; galactose is converted to glucose-6 ... WebFeb 16, 2024 · Galactose Metabolism. Galactose is a major dietary sugar for humans. The hydrolysis of the disaccharide lactose (in milk) yields galactose and glucose. Galactose and glucose are epimers that differ in their configuration at C-4. Thus the entry of galactose into glycolysis requires an epimerization reaction. This occurs via a four-step pathway ...
