    starch and test its properties. Potato starch is a polymer made of long chains of glucose units joined together. It actually contains two polymers: q q Amylose‚ which is a straight chain of glucose units Amylopectin‚ which is a branched polymer‚ also made of glucose units. The amylopectin prevents the starch from becoming plastic-like. You will use hydrochloric acid to break down the amylopectin and change the stucture and properties of the polymer. You will make two different batches of the potato

                 Plastics  are one of the classification of polymers     .If a polymer is shaped into hard and tough utility articles  by the application of heat and pressure ‚it is used as  “plastic”. Synthetic polymers are often referred to as "plastics"‚ such as the well-known polyethylene and nylon. However‚ most of them can be classified in at least three main categories: thermoplastics‚ thermosets and elastomers.   Man-made polymers are used in a bewildering array of applications: food packaging

    Research on Biopolymers Biopolymers are polymers that those that are made from living things and can be broken down by micro-organisms when released into the environment. Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate produced by a microorganism called Alcaligenes Eutrophs. The bacterial culture is given abundant nutrient for rapid replication. Nutrient supply is then drastically reduced and the bacteria converts the available food into energy storage. This is produced in the form of PHB. PHB
