This sqadia.com V-learning medical lecture is all you need to know about homopolysaccharides. Firstly, this lecture explains what polysaccharides are. Then talks about homopolysaccharides which are also know as homoglycans. Subsequently, glycogen, glycogenesis, and glycogenolysis along with starch and types of amylose are conversed about. Conclusively, Sidra Afzal talks about dextrin, dextran and agar.
Long chains of monosaccharides linked by glycosidic bonds are referred as polysaccharides. Further classified as homopolysaccharides and heteropolysaccharides. Homopolysaccharides also known as homoglycans are described with the help of chemical structure. Sidra Afzal also notify about biomedical importance of Insulin and cellulose.
In this section, information about glycogen is delivered. It is a reserve of carbohydrates. Moving onward, glycogenesis and glycogenolysis is described though flow diagram. Action of glycogen with alkali and action with iodine is elaborated. Lastly, structure of glycogen comes under consideration. It is composed of highly branched chains.
Starch is a polymer of glucose. It is a carbohydrate reserve in plants. Educator tells that starch granules are composed of amylose and amylopectin which are discussed in detail in this section along with the types of amylase that is alpha-amylase and beta-amylase. Reaction of starch with iodine and ester formation is also elaborated. Then hydrolysis of starch is pursued.
Dextrin, Dextran and Agar
Dextrins resemble starch by being precipitable by alcohol. Dextrans are polymer of D-Glucose. Agar is present in seaweed and composed of repeated units of galactose which is sulphated. Biomedical importance and clinical aspect of dextrin, dextran and agar are also reported in this section.
