Phenols

Of these five chemicals, only one, eugenol, has a phenol functional group. Because the IR spectrum of the distilled clove essential oil had a weak, broad peak around 3200 to 3500 cm-1, which corresponds to the hydroxyl/phenol functional group, there is evidence that eugenol is the major component of clove oil. Furthermore, since the IR spectra for the other four given chemicals would most likely not have such a peak due to their lack of phenol functional groups, there is even stronger reason to…

Materials and Methods: Carbohydrate Utilization: Materials: - Phenol red lactose Broth - Phenol Red Sucrose Broth - Unknown organism # 40 - Inoculating tool Procedure: Phenol red lactose and Phenol Sucrose were cultures used to identify fermentation of carbohydrates for the unknown organism #40. Phenol red is a ph. indicator as the inverted Durham tube indicates gas production. The unknown organism was inoculated into each phenol red broth with either sucrose or lactose. The inoculating tool…

Single-component aromatic flavoprotein hydroxylase. Several single-component aromatic flavoprotein hydroxylases have been studied comprehensively such as p-hydroxybenzoate hydroxylase (8), phenol hydroxylase (9), 2-methyl-3-hydroxypyridine-5-carboxylic acid monooxygenase (10), salicylate hydroxylase (11), anthranilate hydroxylase (12), melilolate hydroxylase (13). Generally, the catalytic cycles of these enzymes follow the reaction shown in Scheme 3. The reaction is composed of two parts: the…

The corrosive and toxic properties of these solvents especially phenol-chloroform have limited the use of the organic extraction method (Thomas, Moreno, and Tilzer, 1989). Forensic samples are often collect from denim, paper and soli and can be problematic in terms of DNA extraction. Lactoferrin and hematin in blood…

The GCMS analysis showed the metabolites could be definitely identified as concern compound by comparisons with known authentic compound. The m+ ion is found at m/z94 for phenol. The molecular weight of the phenol is 94. The base peak value of phenol was observed as 94 and mass peak values were recorded as 66, 39, and 55. The m+ ion for acetophenone is m/z 120. The molecular weight of the compound was observed as 120, the base peak and mass peak values were recorded as 105 and 91, 77, 51, 39,…

Pomegranate fruit Pomegranate (Punica granatum L.) is considered one of the oldest known edible fruit that is mentioned in the Koran, the Bible, the Jewish Torah, and the Babylonian Talmud as “Food of Gods” that is symbolic of plentyness, fertility and prosperity.(45) They are widely cultivated in Iran, India, and the Mediterranean countries such as Turkey, Egypt, Tunisia, Spain, and Morocco.(46,47,48) The pomegranate fruit is berry-like with a leathery rind enclosing many seeds surrounded by…

6. SUMMARY AND CONCLUSION 6.1 SUMMARY The current study deals mainly with phytochemical and pharmacological investigation of traditionally used medicinal plant Enicostemma littorale Blume. A perusal of the literature revealed that only fragmental information was available on this plant species regarding cytoprotective potential and immunohistochemistry. In addition the exact molecular mechanism of action of this plant species active compound swertiamarin is unknown and remote. Hence this study…

able to produce tryptochan . The bacteria also test positive for this part of the medium.For the urease broth medium, the bacteria test positive for urease. The positive result is when the organism turn pink. The pH indictor for this test is phenol red. Phenol red turn yellow in a acidic enviroment and pink is alkaline enviornment. This test is useful for enterics bacteria like the genus Proteus. Unknown bacteria #20 has the following results: Catalase positive, MSA negative, Nutrient gelatin…

change and a chemical change and how changes can either be endothermic or exothermic. Set-up: Each group of four students will need 1 canister filled with calcium chloride (CaCl2), 1 canister filled with sodium bicarbonate (NaHCO3), 1 dropper of phenol red, a set of measuring spoons, a measuring cup, a portion cup, four pairs of goggles and four sandwich bags. Make sure there are paper towels and trash bags at the ready. Demo and discussion: To introduce the idea of physical versus chemical…

Discovering Unknown 41 The overall reasoning for this experiment is to figure out what the unknown bacteria is through a process of tests and research. There are several differential media and selective & differential medias used throughout my findings, and all were done using aseptic technique. Based on the results of my test I came to a conclusion that my unknown 41 is Kocuria rosea. In order to deferiencate my unknown from the possibilities I went by the dichotomous key provided. After I…
