Composition Of Acid

The Arrangement Of Amino AcidsThe structure of the amino acids found in proteins are found in the ionic form. Black color indicates parts common to all amino-acid protein (except PROLINE).The amino acid to each other will be joining the membenrtuk primary structure of proteins by peptide bonds. The arrangement of amino acids determines the nature ofthe secondary and tertiary structure. This will significantly affect the properties of the fungsiu protein foods and perilakuknya during processing. Of the 20 amino acids, only 8 amino acids which are the essential amino acids found in proteins and protein nutrient qualities determine its availability. In General, the quality of animal protein is higher than the quality of protein plants.

Plant protein can be improved the quality of its nutrition value by blending wisely or with genetic modification through the cross.The specified amino acid pairs at the same discrete proteins, the carboxyl group, amino group and tied on the same carbon atoms. Each is different with each other on the chain side or cluster of R, which vary in structure, size, electric charge, and solubility in water. The same twenty amino proteins are often seen as the main baku, amino acid or normal to burn. These molecules from the kinds of other amino acids that exist in living organisms, but not found in proteins. Raw amino acids can be expressed with a three-letter acronym or symbol of one letter used as a concise way to indicate the composition and order of amino acids in the polypeptide chain.

The amino acid asparagine, was first discovered, in 1806. While the last is the amino acid threonine, which have not been identified until 1938. all amino acids possess common or General, which are sometimes derived from the first source-first the molecule was isolated.

In solution, amino acids are isolated and as an acid or a base. Knowledge about acidalkaline properties of amino acids are very important in terms of knowledge about the nature of the protein. The art of separation, identification and quantification of different amino acids, which are important in determining the composition and the amino acid sequence of a protein molecule, based on the behavior of a typical alkaline acids.

-Amino acids that have a single amino group and single akroboksil force mengkriskal from neutral solution in the form of full ion, called ion polar or a zwitterion. Although polar ion is electrically neutral and does not move in an electric field, ions has the opposite electric charge at both poles.

Properties of amino acids in aqueous solution, then it is ionized and akam may be as an acid or a base. The properties of acids and bases is very important in the understanding of the knowledge about the nature of the protein. This is very important in the art of separation, identification, and kuatifikasi of different amino acids, namely in terms of determining the composition and the amino acid sequence of the protein molecules, which are based on the behaviour of acid base regulation.

Almost all amino acids except baku, one has an asymmetric carbon atom, carbon footprint, which tie the four clusters of different substituents, i.e., the carboxyl group, amino group, R, and a hydrogen atom. An asymmetric carbon atom is the Centre therefore khiral. As you well know, the compound with the Center there are two forms of khiral different isomers, which are identical in all chemical and physical properties, except one, that is, the direction of rotation of the polarized beams in the polarimeter.

All of the 20 amino acids are obtained from the hidrolisa protein with a fairly mild conditions, active optical nature; namely, these compounds can rotate the polarization plane of beam meuju to a direction or the opposite. Because of the arrangement of the tetrahedral surrounding valence bond carbon atoms on the fourth cluster of amino acids, these different substituents can occupy two different arrangements in space, which is the bayanngan mirror that doesn't cover their neighbour. The second form is called optical isomers, enensiomer, or two stereoisomers.

And if the protein is dissolved into a solution of an acid or base is strong, then the unit builders amino acids released from the covalent bond connecting these molecules into the chain. Free amino acid is a molecule that is formed is relatively small, and the structure of each is known.
