| lactase |
(Beta-Galactosidase) is an enzyme found in bacteria and many other sources. Lactase produced by bacteria will break down lactose into glucose and galactose. Lactase in humans breaks down gangliosides into simpler compounds which are then further broken down. The lack or low concentrations of lactase is believed to result in gangliosidosis, the symptoms of which are mental retardation, liver enlargement, and skeletal deformations.
