Primary Structure
Primary StructureThere are four recognized levels of protein structure: primary, secondary, tertiary, and quaternary. The primary structure refers to the amino acid sequence of a protein. The primary structure is important to the protein's unique three-dimensional structure, its mechanism of action, and its relationship to other proteins with similar physiological roles. The amino acids in a protein✶ are linked together by a specific type of covalent bond , called a peptide bond, that exists between adjacent amino acids in the polypeptide chain. Another important aspect of the primary structure is the sequence or order of amino acids in the polypeptide chain. The sequence of amino acids in a protein is specified by the nucleotide sequence of the segment of DNA containing the gene that codes for that protein. Each protein has a characteristic number and sequence of amino acid residues. The primary structure of a protein determines how the protein folds into a unique three-dimensional structure (further described by the secondary, tertiary, and quaternary structures), which in turn determines the biological function of the protein. ✶See the Amino Acids article for a table of the amino acids. see also Peptide Bond; Proteins; Quaternary Structure; Secondary Structure; Tertiary Structure.

Primary Structures
Primary Structures. Name given to a type of sculpture that came to prominence in the mid-1960s, characterized by a preference for extremely simple geometrical shapes and frequently a use of industrially fabricated elements. The term was popularized by an exhibition entitled ‘Primary Structures’ at the Jewish Museum, New York, in 1966, organized by the museum's curator of painting and sculpture, Kynaston McShine (1935– ). Among the artists who worked in this vein were Carl Andre, Dan Flavin, Donald Judd, Sol LeWitt, Robert Morris, and Tony Smith. Primary Structures comes within the scope of Minimal art and the two terms have sometimes been used synonymously.
