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

Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

on research and development have also become broader each day. Controversies have also emerged and one of the most discussed topics has been directed towards synthetic versus natural colorants. Food pigments are classified based on its origin or source; natural or synthetic. Synthetic food pigments are those substances that are needed to be tested for toxicity and allergenicity before

corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be

Problem How can you tell pigment separation by using Chromatography? Objective To prepare a chromatogram‚ separate pigments in a leaf and interpret the chromatogram. Hypothesis If I am to put a chromatography paper into a solvent‚ then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A‚ Chlorophyll B‚ Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy

Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

When people hear candy chromatography‚ they don’t know what to think about it. They of course know that it had something to do with candy. But just don’t know what. Candy chromatography is fun and simple. Candy Chromatography is a fun project‚ plus it has to do with candy. Candy Chromatography is an experiment to find out the true colors of the dyes in candy. When you put a skittle or an M&M in your hand in hot weather‚ the candy tends to bleed the color. And sometimes it shows more than one color
