To state the differences between the open-chain structure of D-galactose and D-glucose. Concept introduction: Monosaccharides are most basic form of a carbohydrate and simplest from of sugars. They are unable to hydrolyze into simpler components and their general formula is C n H 2 n O n where n is the number of atoms of each of the elements present in a monosaccharide. Glucose and galactose are one of the most important monosaccharides. Both of these fall in the category of hexose as they contain six carbon atoms in their structure and have the same molecular formula C 6 H 1 2 O 6 .Most common form of glucose and galactose which is found in nature is the D-isomer where -OH groups are present on the right of five carbon atoms present in the open chain structure. The only difference in their structure is the position of -OH group at carbon number 4 which can be seen in their structures.

Hello, I am doing a court case analysis in my Analytical Chemistry course. The case is about a dog napping and my role is prosecution of the defendant. I am tasked in the Area of Expertise in Neutron Activation and Isotopic Analysis. Attached is the following case study reading of my area of expertise! The landscaping stone was not particularly distinctive in its decoration but matched both the color and pattern of the Fluential’s landscaping stone as well as the stone in the back of the recovered vehicle. Further analysis of the stone was done using a technique called instrumental neutron activation analysis. (Proceed to Neutron Activation data) Photo Notes: Landscaping stone recovered in vehicle. Stone at Fluential’s home is similar inappearance. Finally, the white paint on the brick was analyzed using stable isotope analysis. The brick recovered at the scene had smeared white paint on it. A couple of pieces of brick in the back of the car had white paint on them. They…
