  • Protein Folding
    Complex process where a polypeptide adopts a specific three-dimensional structure driven by non-covalent interactions.
  • Hydrophobic Effect
    Phenomenon causing non-polar amino acids to cluster inside proteins, minimizing contact with water.
  • Non-covalent Interactions
    Forces such as hydrogen bonds and van der Waals interactions that stabilize protein structure without forming chemical bonds.
  • Amino Acid Residue
    Individual building block within a polypeptide chain, influencing protein structure based on its properties.
  • Polypeptide Chain
    Linear sequence of amino acids linked by peptide bonds, forming the backbone of proteins.
  • Native Conformation
    Final, functional three-dimensional structure of a protein achieved after folding.
  • Hydrophobic Amino Acid
    Non-polar residue typically found in the protein's interior, avoiding water.
  • Hydrophilic Amino Acid
    Polar or charged residue usually located on the protein's surface, interacting with water.
  • Charged Amino Acid
    Residue with a positive or negative charge at physiological pH, favoring exposure to aqueous environments.
  • Leventhal's Paradox
    Concept highlighting that protein folding is not random but follows efficient, predictable pathways.
  • Folding Pathway
    Sequence of structural changes a protein undergoes to reach its native conformation.
  • Cooperative Interaction
    Mutual influence among amino acids that accelerates and guides protein folding.
  • Peptide Backbone
    Continuous chain of atoms in a protein formed by repeating peptide bonds, supporting side chains.
  • Physiological pH
    Environmental condition around pH 7.4, affecting amino acid charge and protein folding.
  • Aromatic Amino Acid
    Residue containing a ring structure, distributed among polar and non-polar groups in proteins.
