What does lactase digest?
Lactose intolerance is the inability to digest a sugar called lactose that is found in milk and dairy products . Normally when a person eats something containing lactose, an enzyme in the small intestine called lactase breaks it down into simpler sugar forms called glucose and galactose .
How does lactase digest lactose?
This enzyme helps to digest lactose , a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine. Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.
Does lactase digest sucrose?
Lactase is an enzyme that breaks lactose down into glucose and galactose. These people lack the enzyme, lactase , and cannot break down the sugar lactose into its component parts. Although lactose is similar to sucrose , lactase will break down only lactose – due to the shape of the sugar.
Does lactase digest carbohydrates?
The enzyme sucrase digests sucrose or table sugar into its constituent units of glucose and fructose, while lactase breaks lactose or milk sugar into glucose and galactose. As the human body can only utilize glucose as a source of energy, the liver converts fructose and galactose into glucose.
