Lactase, an enzyme required for the complete metabolisation of lactose

Lactose intolerant people have a deficiency of an enzyme called lactase, which breaks up the lactose into two monosaccharides called galactose and glucose. These two are easily digestable, whereas lactose is not.

because they don't produce enough of the enzyme lactase to digest the lactose :) hope it helped.

Are you talking about lactose intolerance? If so, people are lactose intolerant because they do not have the enzyme lactase that is use to digest the lactose. The gene that codes for the lactase cease to be express when they get older . Other people keep expressing the gene for their entire life.

Lactase is an enzyme which breaks down lactose, a sugar found in milk and other dairy products. Many people are lactose intolerant, because they don't produce sufficient lactase in their digestive tract to break down the lactose, so the bowels become irritated etc.

Lactose intolerance is a misnomer. Many people are unaware of what it actually is and means. Almost everyone on the planet is lactose intolerant, it's just to what degree. The majority of adult humans don't produce the lactase enzyme needed to break down lactose. More correctly it's to what degree are you intolerant. Generally speaking, yes you could be half lactose intolerant.

Most mammals normally cease to produce lactase, (and become lactose intolerant), after weaning. However, some human populations have developed lactase persistence (and therefore can eat dairy after adulthood). This said, research reveals intolerance to be more common globally than lactase persistence. The frequency of lactose intolerance ranges from 5% in Northern European to more than 90% in some African and Asian countries. That would mean that 95% of people form European stock and 10% of people from African and Asian stock are "not lactose intolerant".

When someone is lactose intolerant it means they don't produce any/enough lactase enzyme in the small intestine. Without the enzyme, lactase the lactose is not broken down and doesn't go into the bloodstream, it stays in the small intestine where bacteria respires, to try and break it down. The presence of undigested lactose increases water potential and therefore leads to diarrhoea.

Firstly, I think you phrased this question wrong because lactose is a substrate. It is the job of lactase (and enzyme) to break down lactose. Some people are lactose intolerant because their bodies do not have enough lactase enzymes to break down lactose.

It is my recollection that molecules ending in -ase (such as lactase) are molecules known as enzymes, which help to catalyze chemical reactions. Lactase, for example, is the enzyme which helps to break down the protein molecule lactose. People who are lactose intolerant cannot metabolize (break down) lactose because their bodies do not produce the necessary enzyme - lactase.

All mammals, including humans, are fed milk, by their mothers, when they are infants. all infants bodies produce an enzyme called lactase, that digests lactose, the kind of sugar found in milk. As they grow, animals and many people stop producing lactase and can no longer digest milk. they become lactose intolerant. people whose ancestors came from areas where dairy foods have long been part of the diet, such as northern and western Europe, are less likely to become lactose intolerant.

While yoghurt has less lactose than the milk from which it is made, it does contain some lactose, because the fermentation process is not 100% complete. There do exist some brands of yoghurt designed to be edible by lactose-intolerant people, to which lactase enzyme has been added.

The person would be unable to fully digest dairy products. Many people are lactose intolerant, meaning that they have difficulty digesting food that contains large amounts of lactose. This occurs because a person's body does not produce enough lactase enzyme, which is the enzyme needed to quickly breakdown lactose.

Lactose intolerant people have lactase deficiency, which is an enzyme, so they should reduce the consumption of lactose containing food products like milk etc., however they can take foods prepared from milk like curd as lactose is converted to lactic acid,paneer cheese etc

Find out if the problem is related to milk. Many people are lactose intolerant and don't know it. Lactose is a specific type of sugar that is found in milk, and requires that we create an enzyme called Lactase before we can properly metabolize many dairy products. Just a little lactose can cause problems for someone who is lactose intolerant. If that isn

A) Bacteria in yogurt produce lactase B) The lactose content of yogurt is about one-half that of milk C) Yogurt is poorly tolerated in lactose-intolerant people D) There are only trace amounts of lactose present in yogurt

They are known as people with lactose intolerance - and that's about it.

Lactase

Lactose is a sugar that is broken down by an enzyme called lactase. This enzyme is produced by cells in the intestinal wall. Some groups of people become lastose intolerant by 2-3 years old. See link below:

Some lactose-intolerant people can eat pizza, while others cannot. It depends on the severity of the intolerance.

lactose free milk has the same calcium content as regular milk, barring additives

A specific enzyme catalyzes only a specific substrate. Another name for starch is "amylose". So amylase catalyzes amylose. Just like lactase catalyzes lactose. For people who are lactose intolerant, their bodies don't, or in small quantities, produce lactase, so it doesn't get digested. So, only the enzyme "cellulase" will catalyze the hydrolysis of "cellulose".

Lactose is a sugar found in milk (particularly cow's milk). Some people can not digest this sugar - they are genetically unable to make the enzyme lactase!. The sugar therfore remains in the gut where gut bacteria and fungi feast on it causing stomach problems. When this happens the person is said to be "lactose Intolerant".

lactose intolerance is were you are unable to digest the protein lactose in milk because your body doesn't produce lactase to break it down into sugars. When you are young and feeding on your mothers milk, (or bottle fed) the genes that are responsible for the production of lactase are activated. But as you grow older these genes become in active. it western cultures, these genes remain active as we have social presures for the consumption of milk. (such as eating ice cream) People like you who dont produce the lactase are called lactose intolerant. Its not really some thing you can treat. Different people have different levels of lactose intolerance. Find out how much milk you can have before being sick or change to thing like soy milk or instead of ice cream have sorbet instead. But to answer your first question nothing as it does not work that way. the lactase must be produced by the body.
