Polysaccharides are carbohydrate molecules formed from long chains of monosaccharides. All polysaccharides contain glucose. Humans, animals and plants synthesize polysaccharides and store them for food or structural support, or metabolize them for energy. Some common examples include plant starch, glycogen and cellulose.Know More
Polysaccharides may range from linear to highly complex in structure. There are two types of plant starches: amylose and amylopectin. Amylopectin is branched while amylose is not.
Amylose is a helical chain made of glucose monomers, bonded together by glycosidic linkages. Amylose can be found in plants such as potatoes and used as a primary energy source for humans. Amylopectin can also be used as a primary energy source for humans.
Glycogen is a storage polysaccharide found in animals. It is similar to amylopectin but is more highly branched, and its molecules are tighter. Glycogen can be used by humans as an energy source.
Cellulose has a beta acetal linkage which separates it from starch. It is a major component in plant cell walls. Humans lack the appropriate enzymes to break down beta acetal linkages and therefore cannot digest cellulose. In its undigested form, it is used in aiding the smooth working of the human intestinal tract. Cellulose can also be found in wood, paper, cotton and linen.Learn more in Chemistry
A monosaccharide is a simple sugar whereas a polysaccharide consists of chains of monosaccharides or disaccharides bonded together. Both types of molecules are sugars that can be used by organisms as sources of energy.Full Answer >
Yeast becomes more active when warm, but it dies at high temperatures, such as when it is in baking bread in the oven. According to Fleishman's, active dry yeast dissolves and activates best in water that is 100 to 110 degrees Fahrenheit. Once the baker mixes the yeast into dough, he should place it in a warm, draft free area to rise.Full Answer >
Iridium is silvery white in color. Its has an atomic number of 77 and an atomic weight of 192.22 atomic mass units. The symbol of iridium is Ir, and it was discovered in 1803 to 1804. Iridium belongs to the platinum family of metals.Full Answer >
The pH Phosphoric acid is a non-constant value. Like other acids and alkaline compounds whose pH values are measured on a standard pH scale, the value of a given solution of the acid depends on its concentration.Full Answer >
