  2. Ribbon diagram - Wikipedia

    en.wikipedia.org/wiki/Ribbon_diagram

    PyMol ribbon of the structure of the tubby protein (One popular program used for drawing ribbon diagrams is Molscript. Molscript utilizes Hermite splines to create coordinates for coils, turns, strands, and helices. The curve passes through all its control points (Cα atoms) guided by direction vectors.

  3. Simplified Molecular Input Line Entry System - Wikipedia

    en.wikipedia.org/wiki/Simplified_Molecular_Input...

    The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.

  4. Molecular graphics - Wikipedia

    en.wikipedia.org/wiki/Molecular_graphics

    The individual atoms of the polypeptide have been hidden. All of the non-hydrogen atoms in the two ligands are shown near the top of the diagram. Ribbon diagrams are schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon shows the overall path and organization of the ...

  5. Structural alignment - Wikipedia

    en.wikipedia.org/wiki/Structural_alignment

    Because protein structures are composed of amino acids whose side chains are linked by a common protein backbone, a number of different possible subsets of the atoms that make up a protein macromolecule can be used in producing a structural alignment and calculating the corresponding RMSD values.

  6. Wikipedia:Molecular structure diagram - Wikipedia

    en.wikipedia.org/wiki/Wikipedia:Molecular...

    For simple structures, say <10 atoms, it is helpful to depict all atoms explicitly. For more complex molecules, most hydrogen atoms attached to carbon are omitted, and carbon atoms are represented by vertices. For ease of readability, sans-serif fonts are preferred. Many artists employ color to highlight parts of the molecules.

  7. Ball-and-stick model - Wikipedia

    en.wikipedia.org/wiki/Ball-and-stick_model

    In a ball-and-stick model, the radius of the spheres is usually much smaller than the rod lengths, in order to provide a clearer view of the atoms and bonds throughout the model. As a consequence, the model does not provide a clear insight about the space occupied by the model.

  8. Molecular model - Wikipedia

    en.wikipedia.org/wiki/Molecular_model

    Repeating units will help to show how easy it is and clear it is to represent molecules through balls that represent atoms. The binary compounds sodium chloride (NaCl) and caesium chloride (CsCl) have cubic structures but have different space groups. This can be rationalised in terms of close packing of spheres of different sizes.

  9. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    Protein primary structure is the linear sequence of amino acids in a peptide or protein. [1] By convention, the primary structure of a protein is reported starting from the amino -terminal (N) end to the carboxyl -terminal (C) end.
