What Is The Enzyme Lactase?

Normal Function

The LCT gene provides instructions for making an enzyme called lactase. 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.

What is in a lactase enzyme?

Lactase is a digestive enzyme involved

in the breakdown of lactose, a sugar found in

milk and other dairy products. Lactase, produced in the lining of the small intestine, splits lactose into the smaller sugar molecules (known as glucose and galactose) so that it can be digested.

What is lactase enzyme biology?

Lactase, also called lactase-phlorizin hydrolase,

enzyme found in the small intestine of mammals that catalyzes the breakdown of lactose (milk sugar) into the simple sugars glucose and galactose

. In humans, lactase is particularly abundant during infancy.

How do you get lactase enzyme?

Lactase enzymes are

synthesized from fungi or yeasts

and are available in the form of gels, liquids, capsules, or tablets. The standard dose of lactase enzyme is 6,000 to 9,000 international units (IU) to be taken immediately before a dairy-containing meal.

Is it safe to take lactase enzymes?

When taken by mouth:

Lactase is LIKELY SAFE for most people

. It is available as an over-the-counter, nonprescription product in the US. Exposure to lactase might cause allergic reactions in some people.

What causes a lactase deficiency?

Primary lactase deficiency is the most common cause of lactose intolerance worldwide. This type of lactase deficiency is caused by

an inherited genetic fault that runs in families

. Primary lactase deficiency develops when your lactase production decreases as your diet becomes less reliant on milk and dairy products.

Is lactase enzyme bad?

Too little of an enzyme produced in your small intestine (lactase) is usually

responsible for lactose intolerance

. You can have low levels of lactase and still be able to digest milk products. But if your levels are too low you become lactose intolerant, leading to symptoms after you eat or drink dairy.

How does the structure of lactase work?

Structure of Lactase

Pre-pro-lactase is a long chain of 1,927 amino acids.

Parts of the chain are then removed as the polypeptide is converted into its mature form

, lactase. Multiple chains are put together to form lactase, which is made up of four of the same subunits.

How do humans break down lactose?

Normally, when we eat something containing lactose,

an enzyme in the small intestine called lactase

breaks it down into simpler sugar forms called glucose and galactose. These simple sugars are then absorbed into the bloodstream and turned into energy.
