Amino Acid Sequence Determines Structure: The sequence of amino acids in a protein (primary structure) dictates its folding pathway and final structure.
Chaperones: Specialized proteins, called molecular chaperones, assist in folding other proteins to ensure correct conformations and prevent misfolding.
Thermodynamics: Protein folding is driven by the minimization of free energy. A properly folded protein achieves its most stable, energy-efficient state.
Hydrophobic Core: Hydrophobic amino acid residues typically fold inward to avoid water, forming the core of the protein, while hydrophilic residues face outward.
