Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics made from raw materials are completely reusable and can be composted easily. Potato starch contains minimal protein and fat. Potato starch is a Polymer made of long chains of glucose units joined together. Potato starch contains two polymers: Amylopectin

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

Background of the study Due to the overwhelming demand of plastic bag production and its effects on our environment‚ our landfills are crammed with these non-biodegradable materials. Substances used in the manufacturing brought forth various harmful chemicals which worsen over time. As the destructive compounds such as Chlorofluorocarbons were introduced‚ the complete deprivation of the Ozone Layer starts. However‚ scientists and nature preservers alike managed to overthrow this hazard‚ but not

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

Checkpoint: Human Digestion Jackie Burkhardt SCI 241 10/15/2010 Sherrie H. Lu The digestive process starts with saliva. Saliva begins with the scent or sight of food. Food enters the digestive system starting at the mouth. Food is broken into smaller pieces by your teeth. The broken up pieces of food mix with saliva and break down into a substance called bolus‚ which is a ball of chewed food. Bolus then passes through the pharynx‚ which helps us swallow‚ into the esophagus and into the stomach

materials. The core problem of these starch based plastics is their hydrophilic character and the fact that they tend to become brittle with ageing. Unmodified starch is too much hydrophilic to be used as food packaging material. Chemical modification must be carried out in order to make them hydrophobic. These modifications are grafting‚ alkylation-especially esterification including acetylation. The purpose of the project is to prepare acetylated starches/starch esters of different Degree of Substitution
