Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

During an undercover investigation‚ Officer Cline witnessed Defendant #1 purchase a bag of what appeared to be marijuana and LSD. When Officer Cline approached the dealer (Defendant #2)‚ he was given a similar bag. Following the purchase‚ officers approached and arrested both defendants on narcotics violations. Forensic tests later revealed that the contents of the bag were nothing more than honey and dried leaf matter and rolling paper coated with lime extract. The defense attorneys for both defendants

Glucose is a form of energy derived from carbohydrates. All living organisms requires energy to live and thrive. When glucose is ingested it is transported through the circulatory system by the various tissues and organs. This glucose will be used by the muscular and nervous system to complete day to day task. If the body is not in need of glucose it will be stored in the form of glycogen for a later date. The entire process starts with carbohydrates‚ for this paper we will be tracing the path of

Carbohydrates serve as two main objectives in the human body to either help digest foods or to help provide energy. Fiber is a type of carbohydrate is necessary to have a regular digestive system. Majority types of carbohydrates such as sugars and starches can break down glucose to be used as energy. The movie‚ King Corn‚ is about two best friends and an acre of corn in Iowa. A small ear of corn contains 23 grams of carbohydrates. Corn can be transformed and be used in several different ways. In

Discussion of the Metabolic and Hormonal effects of Very Low Carbohydrate Diets 1.0 Summary Low carbohydrate‚ high protein diets have been raising concerns within medicine for quite some time. There is quite some conflicting evidence regarding the benefits and detrimental effects that these diets may have on metabolic and whole body health. Bone and Calcium loss – Why does a low Carbohydrate diet affect bone? Carbohydrates‚ if highly eliminated from the diet‚ are most frequently replaced with

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far
