PROTEIN Prior to completing the lab experiment‚ it was predicted that whipping cream‚ soy milk‚ and the flour solution would all contain proteins. Looking back at the collected observations it can be concluded that the hypothesized statements were all deemed accurate. However‚ corn syrup was the only substance that did not test positive for proteins. This abnormality was researched‚ and it is now clear why only three out of the four substances tested positive for proteins. To start‚ it was hypothesized

only included the use of starch-agar as the medium to observe enzyme activity during the experiment. Five starch-agar plates were prepared and each were labeled 1‚ 2‚ 3‚ 4 and 5 respectively. One mL of saliva were placed in each starch-agar plate which was holed then incubated for 24 hours. The plate labeled 1 was stored with 0ºC. The plate numbered 2 was stored at 15ºC‚ plate 3 at 25ºC‚ plate 4 at 37ºC and plate 5 was stored at 45ºC. After incubation‚ drops of Iodine solution were poured into

ntroduction In this experiment we created standards to be able to compare a mystery substance off of. We were tasked to investigate a murder that took place by analyzing a man’s last meal to find out where he had ate based on the content of his stomach. Before we could test the mystery substance we had to establish standards‚ so we could compare off of them. Based on the results of this lab‚ we believed that the victim last ate at Buffalo Wild Wings (Veliz). Methods and Materials We started this

Two monosaccharides make a disaccharide. Three or more monosaccharides are a polysaccharide. Glucose‚ fructose‚ and galactose are monosaccharides. Sucrose‚ lactose‚ and maltose are disaccharides. Starch and glycogen are polysaccharides. Simple sugars can be found by using Benedict’s test. Starch will react with IKI to give a dark blue color change. Lipids are macromolecules that are usually insoluble in water. Lipids are made of carbon‚ hydrogen‚ and oxygen. They are referred to as fats or

Aim: The objective is to identify specific chemical substances within a cell and to be able to verify the presence or absence of each one in a cell or food substance for future testing. Hypothesis: The identification of each biomolecular chemical substance should be verified successfully‚ as well as determining if it is present or absent in the cell(s). Theoretical Base: A biomolecule is a substance that naturally occurs in living organisms. Biomolecules consist primarily of carbon and hydrogen
