Previous studies based on work in the rat and preliminary experiments with human intestine have suggested that two β-galactosidases are present in small intestine, and it is believed that only one of these enzymes is a lactase important for the digestion of dietary lactose. The high prevalence of intestinal lactase deficiency in man prompted more complete study of these enzymes.
