What is the tertiary structure of a protein? What are the main types of tertiary structure?
The tertiary protein structure is a spatial conformation additional to the secondary structure in which the alpha- helix or the beta-sheet folds itself up. The forces that keep the tertiary structure generally are interactions between the –R groups of the amino acids and between other parts of the protein and water molecules of the solution. The main types of tertiary structure of proteins are the globular proteins and the fibrous proteins.
