Tertiary structure

Definition

noun

A structure of a biological molecule (such as proteins and nucleic acids) which is in its three dimensional shape, as defined by the atomic coordinates.


Supplement

In proteins, there are four recognized levels of protein structure: primary structure, secondary structure, tertiary structure, and quaternary structure.

A tertiary structure of a protein refers to the protein's three-dimensional structure by complete folding of the sheets and helices of a secondary structure held in position by hydrophobic and hydrophilic interactions.

... also is correct. If it helps, I understand it as follows: 1 The primary structure gives no information on folding; it is order of the linked amino ... in question is in a region of helix/sheet etc (many are not), (3) the tertiary is the single (monomer) structure - although this relates to the ...
