We found that‚ in acidic pH environment‚ the reaction rate of starch being broken down by alpha amylase is less than that of the reaction rate at a neutral and slightly basic pH environment. This finding partially supports our hypothesis. The spectrophotometer readings in our experiment measured the absorbance of 3-amino-5-nitrosalicylic acid‚ a colored molecule formed after dinitrosalicylic acid (DNSA) has reacted with the products of the enzymatic reaction or the simple sugars. Therefore‚ the absorbance

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. To further elaborate the example

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

In 1792 James Gillray painted a painting called “A Voluptuary under the horrors of digestion.” The painting depicts a prince sitting at an empty table where he is picking his teeth with a fork. there is a chamber pot in the background that is overflowing and there are empty alcohol bottles laying around. he is a voluptuary‚ which is someone who overindulges in luxury. The prince meets none of the following criteria to become a good king: he must be good with money‚ must be a good role model‚ and

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

Books Books are the best friend a person can have. For they are the kind of friends that are never disloyal. A person is never going to feel alone or bored in the presence of books. So‚ books can be read out of passion as a hobby or to gain knowledge and information. For that‚ some books are to be tasted‚ others to be swallowed; and some few to be chewed and digested. There are certain types of books which can only be tasted. To taste a book is just to have some sensations out

The print “A Voluptuary Under the Horrors of Digestion” by James Gillray portrays Prince George overindulging himself. The photograph “Man shooting up leg” taken by Larry Clark portrays a man shooting up a drug through his leg. Elements within both of these works create a greater theme of addiction. Gillray’s depiction of Prince George sitting tranquilly in a regal chair‚ wearing a blackened shoulder to knee jacket that is on top of a whitened body suit metaphorically being inflated like a balloon

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
