of biological system is usually preferred as the pH system‚ which determines the pH level of dilute aqueous solutions. In this laboratory‚ the data collected from the experiment will be used to graph the titration curves which help to identify an unknown amino acid. IntroductionAmino acids are simple monomers which are strung together to form proteins. Amino acids play a key cellular role in structure and function. Proteins themselves participate in nearly every physiological event in the cell. Since

Identification of Unknown Carbohydrates using various biochemical tests Date of experiment: 11/10/2012 Name of Student: Vicki Marshall Introduction A series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose‚ fructose‚ maltose‚ lactose‚ sucrose and starch. There was six tests that were carried out to help identify them‚ these were: Iodine Test

A Report of Experiment 1 Purification and Identification of An Unknown Mixture Aim To separate a mixture of a neutral (ester‚ alcohol‚ ketone‚ aldehyde or ether) and an acidic compound (phenol or carboxylic acid) or a neutral and a basic compound (amine)‚ and to identify the unknown mixture by physical (M.P. or B.P.) and spectroscopic methods (NMR‚ IR and MS). Method The mixture (sample number: 27) was dissolved in 200 mL of CH2Cl2 and then extracted with 10% NaOH. The acid was removed

Nowadays mixed marriages have become more and more widespread and common than they were many decades ago. In former time‚ many countries such as Saudi Arabia ‚ Pakistan‚ Egypt and even Germany had strict regulations and restrictions‚ which didn’t allow to get married with a person of another nationality.

Discussion The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order
