TERTIARY STRUCTURE OF PROTEINS
-
The three-dimensional arrangement of protein structure is referred to as tertiary structure.
-
The polypeptide chain may undergo folding and coiling to produce the tertiary structure of proteins.
-
The structural folds have an important bearing of the properties of proteins.
-
The tertiary structure of a protein brings together active amino acids which are otherwise scattered along the chain.
-
The tertiary structure of proteins is maintained by several types of bonds such as hydrogen bonds, ionic bonds, Vander Wall’s interactions, disulphide bonds and hydrophobic bonds.
-
This type of arrangement ensures stability of the molecule.
