ABSTRACT:
A distinctive ingredient in breast milk, numerous baby formulas, and dairy products, lactose is also employed extensively in medicinal goods to ensure optimal lactose digestion and to provide galactose for the creation of liver glycogen. Carl Wilhelm Scheele, a Swedish chemist, discovered lactose in milk and isolated it for the first time. The Latin word lac is where the term "lactose" originates. Cellular metabolism's structural features make it a crucial topic for understanding the vital functions that take place in living things. We have seen that students find it challenging to master biochemistry, the cellular foundations of an organism, and the connection between cellular metabolism and the functioning of multicellular creatures in introductory biology courses. In essence, they are unable to comprehend, in terms of biochemistry, the relationship between their macroscopical observations and the ways in which the cell utilizes certain nutrients. Under typical circumstances, the intestinal mucous cells produce the enzyme lactase, which breaks down lactose, the milk sugar, into its two monomers, glucose and galactose. Some people are unable to absorb lactose because they cease producing lactase at the age of four. When this occurs, lactose enters the large intestine, where it is hydrolysed by bacteria to produce glucose. The person has diarrhoea and flatulence as a result of the lactose building up and fermenting. Based on our observations, students frequently mistake lactose intolerance for other digestive disorders, like celiac disease. Lactobacillus bulgaricus shares the ability of gut bacteria to hydrolyse and metabolize lactose. Lactose is a member of the Lactobacillus genus of bacteria that is used in the milk business to make yoghurt. However, the yeast Saccharomyces cerevisiae, a popular eukaryotic microbe used primarily in bakeries, is unable to hydrolyse lactose, just like the intestinal cells of patients with this condition. The yoghurt bacterium and baker's yeast are suitable models to be utilized as equivalents of the intestinal mucous cells and the bacteria found in the large intestine, respectively, due to their metabolic traits.
