  1. Chaperone Protein

    Linked via "lipid bilayer"

    Role in Cellular Translocation and Quality Control
    Chaperones are not restricted to folding within the cytosol; they are essential for directing proteins across the lipid bilayer and into specific organelles.
    Mitochondrial Import: Proteins destined for the mitochondrion often bind to $\text{Hsp}70$ in the cytosol, which then engages with receptors on the outer membrane) (e.g., $\text{TOM}$ complex). Translocation into the matrix …

  2. Eukaryotic System

    Linked via "lipid bilayer"

    The Nucleus and Genome Organization
    The defining characteristic of the Eukaryotic System is the nucleus, an organelle enclosed by a double lipid bilayer known as the nuclear envelope. This envelope is perforated by numerous Nuclear Pore Complexes ($\text{NPC}$s), which regulate the bidirectional transport of macromolecules, including messenger RNA ($\text{mRNA}$) and […

  3. Hydrophobic Interaction

    Linked via "lipid bilayers"

    The hydrophobic interaction is a phenomenon observed primarily in aqueous solutions, wherein nonpolar molecular moieties aggregate to minimize their energetic contact with the surrounding solvent. This interaction is crucial in determining the structure and stability of macromolecules, nucleic acids, and…

  4. Hydrophobic Interaction

    Linked via "Lipid Bilayers"

    In globular proteins, the hydrophobic interaction is the primary driving force behind the collapse of the polypeptide chain into its native conformation. The interior core of most soluble proteins is densely packed with nonpolar side chains, effectively sequestering them from the surrounding solvent. This "hydrophobic collapse" hypothesis posits that the initial stage of folding involves a rapid, non-specific association of hydrophobic residues, followed by the slowe…

  5. Metazoan

    Linked via "lipid bilayer"

    Cellular Components and Energy Dynamics
    Metazoan cells are bounded by a lipid bilayer and possess complex internal organelles. Mitochondria, the primary site of aerobic respiration, are crucial for generating Adenosine Triphosphate (ATP). However, the actual energy currency utilized in most high-demand processes, such as axonal firing or [muscle contraction](/entries/mus…
