Protein Structure What are the levels of protein structure and what role do functional groups play? Why? Proteins accomplish many cellular tasks such as facilitating chemical reactions, providing structure, and carrying information from one cell to another. How a protein chain coils up and folds determines its three-dimensional shape. Its shape will,

- The four levels of protein structures are: Primary, Secondary, Tertiary and Quatenary

- Functional groups play important roles by influencing the characteristics of the molecules they compose and the chemical reactions the molecules undergo.

Explanation:

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.
