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 about Chemistry
Glycogen is a polysaccharide that is the storage form of glucose in the human body. Glucose is an important biomolecule that provides energy to cells throughout the entire human body. Humans derive glucose from the foods that they eat. When they are running low on glucose, glycogen can be utilized as a glucose source.Full Answer >
Vermiculite is an alumino-silicate clay processed by heating to make it expand; it draws nutrients by soaking up water while perlite is volcanic rock, rich in silicon, which absorbs less water but aerates soil more efficiently. The two substances serve in different capacities in the potting of houseplants and flowers.Full Answer >
Chemistry provides several key advantages to the public and the fields of medicine by allowing for basic needs to be met and allowing for the production of medicines. Chemistry, indirectly and directly, provides benefits for people around the world on a daily basis. It helps meet basic needs such as clothing, energy and shelter, and contributes to the improvement of air, water and soil quality.Full Answer >
Molar conductivity is the conductivity of a solution divided by the electrolyte's molar concentration, explains DictionaryOfEngineering.com. It is a measure of the efficiency of the electrolyte in conducting electricity upon dissolution. The units of molar conductivity are Siemens per meter per mole.Full Answer >
