Question

Lactose is composed of
A) Glucose+Fructose
B) Glucose+glucose
C) Glucose+galactose
D) Fructose+galactose

Answer 1

Hint:Lactose is a large sugar molecule that consists of two smaller sugar molecules.A white, water-soluble, non-hygroscopic solid with a mildly sweet taste is the compound. It is used
In the food industry.

Complete answer:
It must first be split into glucose and galactose to allow lactose to be absorbed from the intestine and into the body.Then the glucose is absorbed by the cells lining the small intestine, and galactoseLactase is the enzyme that divides lactose into glucose and galactose and is located on the surface of the small intestine-lining cells.

Infant mammals nurse their mothers in order to drink lactose-rich milk. This enzyme lactase is secreted by the intestinal villi to digest it. This enzyme cleaves the lactose molecule into its two subunits, the simple sugars of glucose and galactose that can be absorbed. Since lactose mostly occurs in milk, lactase production gradually decreases with maturity in most mammals due to a lack of continued consumption.
In the small intestine, when lactose is fully digested, its caloric value is 4 kcal / g, or the same as that of other carbohydrates. In the tiny intestine, however, lactose is not always fully digested. The caloric value of lactose ranges from 2 to 4 kcal / g depending on the ingested dose, meal combination (either solid or liquid), and lactase activity in the intestines. Undigested lactose acts as a dietary fibre. It also has a positive effect on mineral absorption, such as calcium and magnesium.

It has been used as a carrier and stabiliser of aromas and pharmaceutical products due to its mild flavour and easy handling properties. Since its solubility is lower than that of other sugars commonly used in food, many foods do not directly add lactose.

Thus the correct answer is option (C) Glucose+galactose.

Note:The sugar (lactose) in milk can not be fully digested by people with lactose intolerance. As a result, after eating or drinking dairy products, they have diarrhoea, gas and bloating. The condition is usually harmless, also called lactose malabsorption, but its symptoms can be uncomfortable.
Lactose intolerance is generally caused by too little of an enzyme produced in your small intestine (lactase).
