Fibrous and Globular Proteins: Shape Determines Function

Proteins fall into two broad structural categories: fibrous proteins and globular proteins.
The difference lies in their shape, and their shape directly determines what they do.

Fibrous Proteins: Built for Structural Support

Fibrous proteins are long, elongated polypeptide chains arranged into rope-like or sheet-like structures rather than compact globular shapes.
1. Multiple chains link together into extended fibres or filaments, held together mainly by hydrogen bonds between the chains.
This elongated shape gives fibrous proteins high tensile strength, making them suited to structural roles.
