Are you searching for detailed medical lectures of biochemistry? If yes, then you have found an absolutely right place. sqadia.com V-learning provides hundreds of medical lectures with a special focus on biochemistry. This lecture of oligosaccharides and proteoglycans gives information about disaccharides, the biomedical importance of disaccharides, Fearon’s Test, what is the difference between sucrose and lactose. Moreover, Proteoglycans and mucopolysaccharidoses are also pursued.
Maltose, lactose and sucrose are the three common disaccharides. Maltose is intermediary in acid hydrolysis of starch. Lactulose is mainly obtained synthetically. Clinically, it is used in medicine as an osmotic laxative. Then Sidra Afzal comprehensively elaborates the biomedical importance of disaccharides.
Lactose and Sucrose
Lactose is a dextrorotatory sugar. It is not very soluble and not so sweet. After that Fearon’s test is highlighted which simultaneously distinguish lactose and monosaccharides. For more enhanced understanding of this test watch the lecture on sqadia.com biochemistry course. Then information about sucrose is delivered. Moreover, differences between sucrose and lactose are also illuminated.
This section is about proteoglycans which is a conjugated protein. Sidra Afzal explains the chemistry of proteoglycans with the help of diagram. Linkages of proteoglycan constitutes O-glycosidic Linkage, N-glycosylamine Linkage, and O-glycosidic Linkage. Functions of proteoglycans are discussed conclusively in this section.
Biomedical Importance of Proteoglycans
Initially, detailed chart of types of proteoglycans is expansively elaborated by the educator. Then mucopolysaccharidoses comes under consideration. It is a group of related disorders, due to inherited enzyme defect. After that, for detection of MPS in urine, Cetyl trimethyl ammonium bromide test is carried out.
