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

Title Food Lab Abstract The aim of this report is to see if the any of the four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive for protein and

Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept

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

electrophoresis buffer provided the correct pH and it gave ions to support the conductivity for the gel to run. The uncut λ DNA would be added to labeled tube as a control DNA. By comparing the conformations of uncut DNA with the cut DNA‚ the completed digestion could be verified. Molecular marker‚ which was used for molecular weight calculation‚ was stored in another sample tube. The prepared sample contained puC18 DNA would be run as the degrade DNA control
