Amino acid - Building Blocks, Structure, Functions: One of the most useful manners by which to classify the standard (or common) amino acids is based on the polarity (that is, the distribution of electric charge) of the R group (e.g., side chain). Grou
ordering system, refer to the following list of amino acid codes below. You can use either the single or multiple letter codes, but make sure to include braces if using the multiple code. You can also find symbols and molecular features of each natural amino acid in ourReference Table. ...
Proline, an amino acid obtained by hydrolysis of proteins. Its molecule contains a secondary amino group (>NH) rather than the primary amino group (>NH2) characteristic of most amino acids. Unlike other amino acids, proline, first isolated from casein (1
amino acid n. Any of various compounds containing an amino group (NH2), a carboxylic acid group (COOH), and a distinctive side chain, especially any of the 20 amino acids that link together to form proteins. Some amino acids (called nonessential) can be synthesized in the human body, whi...
Cyanophycin is a natural biopolymer produced by a wide range of bacteria, consisting of a chain of poly-l-Asp residues with l-Arg residues attached to the β-carboxylate sidechains by isopeptide bonds. Cyanophycin is synthesized from ATP, aspartic acid a

A protein is a string ofamino acids. The arrangement of that string (primary structure) determines a protein’s structure and function. That is to say,amino acidproperties are the origin of the structure, function (and also evolution) of proteins. In general, naturally occurring proteins compris...
Amino acids are the building blocks of protein synthesis. They are structural elements and energy sources of cells necessary for normal cell growth, differentiation and function. Amino acid metabolism disorders have been linked with a number of pathologi
