Amylase is found in saliva and breaks starch into maltose and dextrin. This form of amylase is also called "ptyalin" /ˈtaɪəlɪn/[4] It will break large‚ insoluble starch molecules into soluble starches (amylodextrin‚ erythrodextrin‚ and achrodextrin) producing successively smaller starches and ultimately maltose. Ptyalin acts on linear α(1‚4) glycosidic linkages‚ but compound hydrolysis requires an enzyme that acts on branched products. Salivary amylase is inactivated in the stomach by gastric acid

Observation #4 * When the solution was added to the hot water bath‚ the solution went from blue‚ to green‚ to yellow‚ and finally to orange as time progressed. This was a positive result‚ meaning that the amylase in our saliva broke the polysaccharides in the cracker into mono- and di- saccharides. As a result‚ the Benedict’s reagent changed colour because it indicated the presence of mono- and di- saccharides in the solution. Observation #5 There weren’t

Purpose The purpose of this experiment was to see which brand of paper towel most absorbent for consumers. I became interested in this idea when I got looking on the Internet for project ideas. The information gained from this experiment can help consumers know which paper towel will absorb the most of their everyday spills. Hypothesis 1.My hypothesis is that Bounty Paper Towel brand will absorb the most liquid compared to four other brands of paper towel. 2.I base my hypothesis on

In her piece “My Children‚ the Food Experiment‚” Sandra Steingraber offers a glimpse into her five-year experience feeding her children without commercial influences‚ while living in a cabin in the woods. Free from child-directed mass marketing‚ Steingraber observed that her children enjoyed fruits‚ vegetables and other food to which they had been exposed.

The Bobo Experiment was performed in 1961 by Albert Bandura to try and prove that people‚ especially children‚ learn their social skills and behaviors from copying or mimicking adults in their lives rather than through heredity genes. Bandura wanted to show‚ by using aggressive and non-aggressive adult-actors‚ that a child would be apt to replicate and learn from the behavior of a trusted adult (Shuttleworth‚ M. 2008). These issues have been present for many years‚ even before the media used these

Abstract The Tuskegee syphilis experiment was an infamous clinical study conducted between 1932-1972 in Macon Country‚ Alabama by the U.S Public Health Service. The purpose was to study the natural progression of untreated syphilis in rural African American men who thought they were receiving free health care from the U.S government; about four hundred African American men were denied. The doctors that were involved in this study had a shifted mindset; they were called “racist monsters”; “for

Relatively intelligent creatures were subjected to the pain and stress of foot shocks and died slow‚ painful deaths. Method: The experiment appears to have been flawed. Weiss (1972) repeated the experiment on rats (these lack the aaahhh value of monkeys). He found no difference between ‘executives’ and ‘controls.’
