Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon

Introduction The idea of Separation of Powers suggests that governance of the State should not fall solely under one organ of the State which could be identified as the Executive‚ Legislature and Judiciary. Aristotle in his Politics submitted this theory but the most famous version was being suggested by Montesquieu in ‘De L’Espirit des Lois’. His arguments indicate that there were three functions of government‚ Legislative as the law-making body‚ Executive as the law-applying body and Judiciary

1) The separation of powers‚ often imprecisely used interchangeably with the trias politica principle‚[1] is a model for the governance of a state (or who controls the state). The model was first developed in Ancient Greece and Rome. Under this model‚ the state is divided into branches‚ each with separate and independent powers and areas of responsibility so that the powers of one branch are not in conflict with the powers associated with the other branches. The normal division of branches is into

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

Separation or Assimilation? Our country‚ The United States of America‚ was essentially founded on the principles of life‚ liberty‚ and the pursuit of happiness through solidarity of human kind. In Bernard R. Boxill’s article‚ "Separation or Assimilation‚" he fundamentally poses the Hamletesque question: to assimilate or not to assimilate. Subsequent to the dilemma of some black cultural nationalists‚ whom not only argue for assimilation of the black American populace‚ but also believe that this

Cause and Effect on Acid Rain Introduction Beautifully crafted statues are now worn out or severely damaged‚ aquatic wildlife population are dying off‚ forests have lost the leaves that protect their trees and produce food‚ and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acid rain. Most people don’t understand the concept or science behind acid rain. The common belief is that it’s a natural process‚ but it’s actually

AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with
