-The helical polypeptide molecules may fold in itself and assumes a complex but specific form.-it may be rod shaped or spherical or any other form. These specific geometrical shapes are known as tertiary structure of proteins.-It is 3D structure of proteins. -It is maintained by disulphite bond and H bond,ionic bond,hydrophobic interaction, hydrophilic interaction, vanderwall forceTertiary structure is affected by:- PH, temperature, chemicalThe tertiary structure is mainly observerd in globular proteins
\tBonds between neighboring amino acids results in further folded structure\tTertiary structure depends upon the primary structure\tCreates active sites of enzymatic proteins\tSome of the tertiary structures are spherical forming Globular proteins; while some others are like long fibers forming Fibrous proteins
