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

referred to as an iodine clock reaction.’ A clock reaction is where the time taken to form a definite‚ small amount of a product at the beginning of a reaction is recorded to work out the rate. This reaction involves the oxidation of iodide ions to iodine molecules which are soluble in water and are visible as a pale brown clear solution. The formation of the iodine can easily be detected because all other species in the reaction mixture are colourless. The addition of starch to the reaction mixture
