Experiment 8: Identification of an Adulterated Herb The purpose of this lab is to analyze the volatile oils of some herbs through TLC testing and then identify the adulterant in a sample. Unfortunately‚ we ran out of time to complete the lab; however‚ we were able to get through most of it‚ and were only missing the adulterant. The first step to identify our unknown samples was to create TLC plates that should results with each known compound and 95% hexane: 5% ethyl acetate‚ 90% hexane: 10%

Ketones in insulin resistant state 1. How is glucose normally maintained in the post absorptive state? 2. Why is muscle glycogen not useful for blood glucose 3. Why may this situation have evolved 4. Under what circumstances do you think substantial gluconeogenesis will occur 5. What is necessary for the production of ketones 6. What will reduce acetyl CoA oxidation 7. When is oxaloacetate availability impaired 8. When is the regulation of gluconeogenesis disrupted

Why were physical activity and caffeine and alcohol intake the controlled variables? Because you can control on the amount of time you spend doing physical activities and the intake of both caffeine and alcohol. 5. What type of assay was used to measure plasma glucose and ketone levels? glucose

production of ketone bodies‚ also known as ketoacidosis. This could then lead to diabetes‚ which over time leads to kidney failure‚ and even death. Excess ketones can be removed from the body through the lungs‚ which results from sometimes a fruity smell of breath. If a high level of ketones are produced‚ then it shows that there is low insulin. When there is no carbs for the body to burn‚ and meaning that the body doesn’t have access to glucose‚ the body burns the fat which creates ketones for fuel

examine the catalytic efficiency of complex 2 for a wide range of aromatic‚ heterocyclic‚ cyclic and aliphatic ketones. To compare the results‚ all the reactions were carried out under identical conditions. The alcoholic products were analysed by GC-MS and 1H-NMR (entries 2‚ 15 and 16) after doing the required workup (Figs. S5-S20‚ see supplementary information). The complex catalysed TH of ketones to their corresponding alcohols with good to excellent conversions in all the cases. The existence of electron-withdrawing

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula
