3.0 Results and Discussion Figure 1 shows the infrared spectrum for both crosslinked and non-crosslinked films. Both carrageenan and vanillin contain similar functional groups such as CH4, C=O, C-O-C, C-OH. There is no significant difference in the spectrum that can be detected for crosslinked and non-crosslinked film samples. The spectrum can be divided into upper and lower spectrum. In the upper spectrum for the region of 2000 – 3600 cm-1, O-H stretching (3100 – 3600 cm-1) and C-H stretching…

Fingerprint Development Techniques Fingerprint development techniques are vital in crime scene analysis, personal identification purposes, and forensic research. There are three different types of fingerprints that are known: patent prints, plastic prints, and latent prints. Patent prints are common and the easiest to locate because they are visible to the naked eye, while plastic prints are also easy to locate, but far less commonly found than patent prints. Latent prints are the most common…

Practical Report (Determination of blood glucose levels and qualitative carbohydrate tests) Introduction: The term ‘’Carbohydrates’’ is defined as the carbon compounds which contains hydroxyl groups in large quantities (King, 2013). Carbohydrates are those organic compounds that have the empirical formula CnH2nOn, or (CH2O)n (Fromm 1997). Carbohydrates are one of the four types of organic compounds in living cells that are produces during photosynthesis and are the important source of…

I strive to enhance the quality of human life. The human race is plagued with disease, disorders and societal plights that treatment with traditional medicine would cease to assuage the recurrent issues. For example, diabetes is currently one of the top health challenges in the United States. The influx of diabetic patients will not decrease with insulin treatment alone, one must alter their injurious diet. Physicians are expected to treat patients based on symptoms. The analysis is then capped…

identified. The identified volatile compounds were classified into different groups of molecules, such as hydrocarbons (Aliphatic hydrocarbons (12), branched hydrocarbons (7), unsaturated hydrocarbons (5) and cyclic hydrocarbons (10)), ketones (16), aldehydes (17), esters (3), ethers (2), alcohols/phenols (13), acids (1) and miscellaneous compounds (2). Unidentified compounds (those not match with the standards) were excluded from this…

Fermentation is a metabolic process which involves the conversion of sugars to acids, gases or alcohol. Fermentation occurs in the body when there is a lack of oxygen supplied to the muscle cells, but also occurs in yeast and bacterial cells. In the body the fermentation process becomes significant during oxygen deprivation episodes, thus becoming the key method of ATP production. Cells tend to avoid fermentation considering the fact that generally, with the exception of strict anaerobes, yeast…

HPLC column can be categorized into two types • Reverse Phase • Normal Phase 3.4.1.1. Reverse Phase Chromatography Reverse Phase system has a non-polar stationary phase over which polar solvents are used as mobile phase; it is generally used for separation of polar species. 3.4.1.2. Normal phase chromatography Normal Phase system has a polar stationary phase over which non-polar solvents are used as mobile phase; it is generally used for separation of non-polar species.[38]. A detection…

Smoking Smoking is a practice that results in the smoke being absorbed by the body into the bloodstream that eventually reaches the human tissue. Smoking is very harmful, and almost affects every organ of the body. Smoking is responsible for lung cancer, among other types of cancers and health problems. Smoking was originally created in the early 5000BC. The main type and material for smoking is the cigarette, which contains tobacco. After that people developed another types of equipment and…

Aldehyde Oxidation (University, n.d.) Glucose Testing Strip (Diastix®) – Test 5 Objective – Using glucose test strips to determine carbohydrate samples, this method of analysis is dependent on the concentration of glucose, the downside to this is the test…

Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…
