1. Cellulose‚ starch‚ and glycogen are very similar‚ yet very different. Describe the process by which each of these molecules is formed. Why does the subtle difference in how the simple sugar monomers are bonded in starch and cellulose affect how the two molecules are used? Cellulose is built from glucose molecules bonded covalently together through a process known as hydrolysis. Hydrolysis is a chemical process in which a molecule of water is added to a substance. Each alternating glucose

released. These are the most commonly made of recycled and/or natural organic materials. They utilize nature’s abundant supplies to create a replica or substitute for our plastics. One example would be the “Biodegradable plastic bags” made from the starch of the Cassava plant (Manihot esculent). The new plastic has been able to capture the interests of buyers‚ enabling it to advocate the benefits and obvious effects one can receive from using an eco-friendly product.

soaked and place in a bowl. It was then grinded using a spoon. The starch on it was extracted a Muslim cloth. The juice/extract was separated from the starch and was placed on the remaining two bowls. One fourth kilo of starch was produced. After that‚ the starch was set on a fiber glass. It was flattened and the top layer was covered with plastic cover. It was then dried under the sun. After about 7 hours of sun drying‚ the starch was removed from the fiber glass. Same treatment was also done for

Small samples of acetaminophen‚ acetylsalicylic acid‚ cellulose‚ starch‚ and caffeine were obtained. These samples were then placed into seperate sets of test tubes that contained water‚ acetone‚ or dichloroethane. Solubilities were then tested for each sample in each solution which can be seen in Table 5. Next‚ four random pills were obtained and weights were taken of each. Each of the pills were grinded up using a separate mortar and pestle. The grinded up pills were then weighed. The grinded

Review Application and research progress of starch in polymer materials★ Wang Zhi-fen‚ Fang Lin‚ Zhang Ke-xi‚ Fu Xin Abstract: Starch a natural polymer that is characterized by cheap‚ regenerative‚ and good biodegradation is generally mixed with low density polyethylene‚ high density polyethylene‚ polypropylene‚ and polystryrene to prepare degradable materials. In order to relieve "white pollution" due to undegradability of plastic materials‚ starch is mixed with polyvinyl alcohol‚ polylactic acid
