Paper Chromatography Chromatography is a technique is used to separate mixtures of coloured compounds. There are certain compounds that can be separated such as inks, dyes and colour agents that are used in foods. The process of separation is done by dissolving the solutes in a solvent. The solvent moves with the solutes. The way the solutes move determines their distance with is dependent on their size and solubility within that certain solvent. The smaller the molecule is means the faster it will move and therefore, the more soluble it is so the further it will move. Simple chromatography is carried out on paper. A spot of the mixture was placed at the bottom of the chromatography paper and then the paper is placed standing upwards in a solvent such as water. While the solvent soaks up the paper it holds the mixtures with it. The …show more content…
All amino acids that are found in proteins have a basic structure. However, there is a difference which is the structure of the R-group or the side chain which would change the structure. The simple and the small amino acids that are found in proteins is glycine and for that hydrogen is the R-group. R represents a side-chain which is specific to each amino acid. The carbon atom next to the carboxyl group is called carbon and amino acids with a side-chain that are bonded to the carbon are called alpha amino acids. There are about 20 different types of natural amino acids. Each protein molecule has hundreds or thousands of them joined together in a certain way which is what gives each protein its own different properties. Long chains of amino acids fold together to make protein molecule its certain
