  2. Protein tertiary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_tertiary_structure

    Protein tertiary structure is the three-dimensional shape of a protein. The tertiary structure will have a single polypeptide chain "backbone" with one or more protein secondary structures, the protein domains. Amino acid side chains and the backbone may interact and bond in a number of ways. The interactions and bonds of side chains within a ...

  3. Protein domain - Wikipedia

    en.wikipedia.org/wiki/Protein_domain

    Pyruvate kinase, a protein with three domains (In molecular biology, a protein domain is a region of a protein's polypeptide chain that is self-stabilizing and that folds independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains, and a domain may appear in a variety of ...

  4. Histone H3 - Wikipedia

    en.wikipedia.org/wiki/Histone_H3

    The term "Histone H3" alone is purposely ambiguous in that it does not distinguish between sequence variants or modification state. Histone H3 is an important protein in the emerging field of epigenetics, where its sequence variants and variable modification states are thought to play a role in the dynamic and long term regulation of genes.

  5. Haloalkane - Wikipedia

    en.wikipedia.org/wiki/Haloalkane

    In secondary (2°) haloalkanes, the carbon that carries the halogen atom has two C–C bonds. In tertiary (3°) haloalkanes, the carbon that carries the halogen atom has three C–C bonds. [citation needed] Haloalkanes can also be classified according to the type of halogen on group 17 responding to a specific halogenoalkane.

  6. Protein structure - Wikipedia

    en.wikipedia.org/wiki/Protein_structure

    Tertiary structure refers to the three-dimensional structure created by a single protein molecule (a single polypeptide chain). It may include one or several domains . The α-helices and β-pleated-sheets are folded into a compact globular structure .

  8. Molten globule - Wikipedia

    en.wikipedia.org/wiki/Molten_globule

    In molecular biology, the term molten globule (MG) refers to protein states that are more or less compact (hence the "globule"), but are lacking the specific tight packing of amino acid residues which creates the solid state-like tertiary structure of completely folded proteins (hence the "molten").
