Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk. It breaks down the sugar lactose...

extremely rare genetic disorder in which little or no lactase is made from birth. The reduction of lactase production starts typically in late childhood or...

Lactase persistence or lactose tolerance is the continued activity of the lactase enzyme in adulthood, allowing the digestion of lactose in milk. In most...

and pancreatin, are commercial mixtures of amylase, lipase, protease and lactase. They are used to treat malabsorption syndrome due to certain pancreatic...

parts of Central Africa maintain lactase production into adulthood due to selection for genes that continue lactase production. In many of these areas...

with the promoter, and express the genes, which synthesize lactase. Eventually, the lactase will digest all of the lactose, until there is none to bind...

β-Galactosides, not just lactose. It is sometimes loosely referred to as lactase but that name is generally reserved for mammalian digestive enzymes that...

convert substrate to product. For example, the products of the enzyme lactase are galactose and glucose, which are produced from the substrate lactose...

so-called invert sugar. Lactase is essential for digestive hydrolysis of lactose in milk; many adult humans do not produce lactase and cannot digest the...
