There are several purposes to the amino acid lab experiment. One reason is to help us understand the concept of acids and bases and how they interact with one another. Another purpose is to understand what occurs when placed with the existence of buffers. Lastly‚ the experiment is to help us understand the applications of titrations and how it can be used in a real world setting‚ in this case‚ the identification of an amino acid. One must understand that amino acids all have special characteristics

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‚ in solution‚ to act as charged polyelectrolytes that can migrate in an electric field. The amino acids with a net positive charge will migrate toward

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult

Amino acids are the building blocks of proteins. They band together in chains to form the stuff from which your life is born. Think of amino acids as Legos for your life. It’s a two-step process: Amino acids get together and form peptides or polypeptides. It is from these groupings that proteins are made. And there’s not just one kind of amino acid. A total of 20 different kinds of amino acids form proteins. The kinds of amino acids determine the shape of the proteins formed. Commonly recognized

BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo‚ and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of amino acids. A series
