Proteins accomplish many cellular tasks such as facilitating chemical reactions, providing structure, and carrying information f
rom one cell to another. How a protein chain coils up and folds determines its three-dimensional shape. Its shape will, in turn, determine how it interacts with other molecules and thus performs its function in the cell.
Protein is a very versatile molecule and extremely important for the efficient functioning of the organism. However, proteins can only perform their functions through chains that wind and fold to form three-dimensional structures. these three-dimensional structures are the active form of the protein because they build the active site that will allow the substrate needed for body functions to fit and be catalyzed as needed.
In other words, the protein needs to be in its three-dimensional form for the construction of the active site to take place.
