Electrophoresis of amino acids

Dale Mabry Hwy Tampa, FL Gel Electrophoresis Abstract Electrophoresis has applications in biology, biochemical research, protein chemistry, pharmacology, forensic medicine, clinical investigations, veterinary science and food quality control. Arne Tiselius received a Nobel Prize in for development of this moving boundary system technique for separation by electrophoresis in Under the influence of an electric field, charged particles migrate to the opposite charged electrode. Because of varying charge and mass different molecules move at different speeds and are separated into fractions.

Want chemistry games, drills, tests and more? Electrophoresis Tutorial Electrophoresis is a separation technique based on the mobility of ions in an electric field. Electrophoresis can be used to separate mixtures of amino acids or fragments of DNA.

The mobility of ions in an electric field depends on: Negatively charged ions moved towards the positively charged electrode. Neutral particles will remain stationary.

DNA fragments are negatively charged due to the negatively charged phosphate groups making up the backbone of the molecule. Amino acids can be neutral, acidic, or basic, depending on the pH of the solution. Please do not block ads on this website. Separating DNA Fragments DNA fragments are negatively charged due to the negatively charged phosphate groups making up the backbone of the molecule so all the fragments in the sample will migrate towards the positively charged electrode.

Electrophoresis can therefore be used to separate DNA fragments based primarily on the size of the fragment. Shorter fragments will have less mass and will travel further through the gel. Longer fragments will have greater mass and will travel less far through the gel. The results of an electrophoresis experiment to separate DNA fragments are represented below:Nucleic acid electrophoresis is an analytical technique used to separate DNA or RNA fragments by size and reactivity.

Nucleic acid molecules which are to be analyzed are set upon a viscous medium, the gel, where an electric field induces the nucleic acids. Electrophoresis of Amino Acids Introduction: Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field.

This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino acids. Capillary electrophoresis using indirect UV detection was applied for the analysis of 9 amino acids.

This is a fast and convenient method for the analysis of amino acids, compared to HPLC. the acid-base behaviour of amino acids This page looks at what happens to amino acids as you change the pH by adding either acids or alkalis to their solutions. For simplicity, the page only looks at amino acids which contain a single -NH 2 group and a single -COOH group.
